     ''A New Era for Microwave Imaging Systems''


Affiliation: Rohde & Schwarz, Munich, Germany


Microwave imaging technology with millimeter-waves is witnessing a new era in addressing the requirements of many applications, e.g., personnel security screening. This is achieved due to the advances in the hardware integration as well as the signal processing techniques involved. Many efforts have been accomplished to bring microwave imaging methods from their conventional lab environment to the real applications space. Many more methods are still yet struggling to see the light apart from the lab bench and the computer simulators. The state-of-the-art technological capabilities of active scanning with wide-band signals in real-time operation is highly attractive for non-destructive testing (NDT) in the industrial applications as well. However, the migration of security imaging systems towards NDT applications is not trivial; as many adaptations and customizations have to be performed. In this talk, an overview on the advances of microwave imaging solutions to serve in the security and industrial domains is presented; followed by a discussion on the associated challenges to extend these technologies further.

    Professor Herbert Zirath


     "Design of millimeterwave multifunction integrated circuits for data     
       communication and remote sensing applications''


   Fellow IEEE, Professor, head of Microwave Electronics Laboratory
   Dept. of Microtechnology and Nanoscience, MC2
   Chalmers University of Technology



The transmission rate of wireless data in the mobile networks is doubling every year due to the increased usage of mobile multimedia services like streaming video, music, television, data transfer in smartphones and laptop-computers etc. This tendency will require continuously improved telecom infrastructure regarding both base-stations and the backhaul communication links. Today, the E-band (71-76, 81-86, 92-95 GHz) is employed increasingly in the networks, allowing multi Gbps data rate.  In a near future however, the E-band will be crowded, and novel, higher frequency bands can to be employed as well. Several hundred Gigahertz bandwidth is available for new communication and sensing applications just waiting to be exploited at frequencies above 100 GHz. Until now, components for making such ‘THz-systems’ have been too expensive, too bulky, too power hungry and nonsufficient in terms of generating enough power for communication systems. With newly developed RFIC-processes, it is now possible to design multifunctional integrated circuits, realizing a full ‘frontend on a chip’ at frequencies well beyond 100 GHz. Recent results from ongoing projects aiming at enabling new applications for next generation mobile infrastructure, 5G, and imaging, up to 340 GHz will be reported. So far, critical building blocks such as LNA, PA, VCO, modulator and demodulator, frequency multiplier, power detector and mixer have recently been developed, and results will be reported. Multifunction front-end circuits such as complete receive and transmit RFICs, mixed signal designs for co-integrated baseband/frontend ICs, and radiometer ICs have also been developed and will be reported as well, including the newly developed D-band frontend chipset demonstrating state-of-the-art bitrate of beyond 40 Gbps.

    Professor Maurizio Bozzi

    ''3D-Printed, Textile, and Paper-based Substrate Integrated Waveguide Components for
       the Internet of Things''

University of Pavia, Italy


A completely new approach to the development of wireless microwave systems is required by the advent of Internet of Things (IoT). The next generation of microwave systems demands a technology that guarantees easy integration of complex wireless nodes, combination of multiple functions in a single device, low development cost, compact size and low weight.

Among the available technologies for the implementation and integration of microwave components and systems, the substrate integration waveguide (SIW) technology looks a very suitable approach, able to satisfy the requirements of the future IoT systems. In fact, SIW technology allows to implement a variety of passive components, active subsystems, and antennas in a simple and cost-effective way, and to integrate entire systems in a single dielectric substrate, thus avoiding complex transitions and undesired parasitic effects.

The choice of the substrate material represents another key point for IoT systems: in fact, depending on the specific application, different requirements are posed. The use of paper, for instance, guarantees the implementation of eco-friendly systems (required in specific fields, e.g., agriculture), a very low material cost, and structure conformability. The use of textile, on the other hand, appears very suitable for the implementation of wearable systems, which can be directly integrated into garments (important, e.g., in biomedical applications). Finally, additive manufacturing techniques like 3D printing represent a rapidly emerging area, which allows the low-cost and ease manufacturing of fully three-dimensional structures.

This presentation will cover the perspectives of microwave systems in the new scenario of the IoT, with particular emphasis on implementation of SIW components and antennas with different substrate materials, including the material characterization, the fabrication process, and the implementation of some prototypes.

      ''Nonreciprocal properties of GHz frequency surface spin waves in      
       nanopatterned ferromagnetic films''
   Faculty of Physics
   Adam Mickiewicz in Poznan, Poland



Nonreciprocal properties of spin waves propagating in ferromagnetic thin films are of potential use in designing miniaturized isolators and circulators, essential elements in microwave technology. Here we study surface spin waves propagating perpendicularly to the external magnetic field in homogeneous or regularly patterned ferromagnetic thin films, the latter representing magnonic crystals. We establish the influence of the periodic pattern on the localization properties of the spin-wave amplitude, showing that the surface character decreases at wavenumbers related to the symmetry points in reciprocal space. We demonstrate that the nonreciprocity can be enhanced by modification of the surface or surrounding of the ferromagnetic film resulting in a strong asymmetry between the dispersion relations of spin waves propagating in opposite directions. Nonreciprocity of surface spin waves allows the formation of band gaps in the spin-wave spectrum. However, nonreciprocity is observed to shift magnonic band gaps to higher frequencies and larger wave vectors, far beyond the boundary of the Brillouin zone. Potential applications of spin-wave nonreciprocity are discussed as well.

      Independent Automotive Radar Expert

      ''Automotive Radar and ADAS on its way to Autonomous Driving''



Automotive radar and thus ADAS based on radar has been in development over decades – in1998 Mercedes-Benz was first to go into series production for premium cars. Until mid 2015 Infineon had sold 10 million 77 GHz chipsets worldwide, Valeo and Hella have sold each more than 2.5 million 24 GHz BSD (Blind Spot Detection) units in 2015 and Mercedes-Benz installed more than 2.5 Million radar units (77 & 24 GHz) into cars in 2015. New cars out of today’s production are widely equipped with a lot of different ADAS units - based on radar (most importantly), lidar or cameras.

In 2012 the “Drive Me” project in Sweden was started by Volvo Cars to put 100 autonomously driven vehicles on the urban roads of Gothenburg until 2017. The aim is to pinpoint the societal benefits of autonomous driving and position Sweden and Volvo Cars as leaders in the development of future mobility. In 2015 the Yutong “iBus” - the intelligent urban bus - has shown its unique capabilities on urban streets. On August 29th 26 km were driven entirely autonomously, incl. stops for passenger getting out and in, respecting traffic lights and passing other vehicles on its way.

The actual status in this entire field, the pro’s and con’s of the different sensor types, as well as their availability and performance will be discussed in general. The trends of future development directions leading towards autonomous driving will be discussed.

       Professor Luca Perregrini


        "Bridging millimeter-wave biophysics, safety and imaging"



Knowledge of tissue dielectric properties in the millimetre-wave spectral range is needed as a starting point for biophysical modelling, to guide future exposure studies, to contribute to the evidence base for regulatory decision-making, and to provide insight into the potential alternative uses of this spectral band. In prior studies, these information were derived by extrapolation using existing models based on measurements at microwave frequencies, but the predictions of these models for higher frequencies were not tested in detail.

In this presentation, the experimental study of ex-vivo tissues at mm-wave frequencies (5- 50 GHz) is reported, which lead to the determination and modelling of the dielectric properties of healthy and tumorous tissues. The results of the study demonstrate a consistent contrast between tumorous and normal breast tissue, supporting the use of ultra-wideband millimetre-wave systems for breast imaging, and offering a potential order of magnitude improvement in spatial resolution over microwave-based systems.

These measurement results have also been used in simulations of the energy deposition in tissues by millimetre-wave devices, thus assessing the safety issues, and in predicting the performance of an archetypal imaging system. The results of these activities will be reported and discussed during the presentation.

      "Theory and Demonstration of Non-Linear Communication System                                               with Harmonic Diversity"
   Wireless Communication Laboratory
   Department of Electrical and Computer Engineering       
   Faculty of Science and Technology, University of Macau, Macao SAR, China


This talk presents the concept, theory and demonstration of harmonic diversity for wireless communication, which makes use of multiple harmonic radiofrequency (RF) channels with respect to the carrier frequency. Unlike the well-documented frequency and space diversities, the proposed scheme does not require multiple RF transceiver front-ends. The advantages of inherent nonlinear characteristics of RF devices are harnessed to produce and process harmonics within single transceiver. The use of harmonic RF channels allows for a significant cost reduction of building blocks so as to lower the system development and manufacturing expenditure compared to current communication systems. Even though distinct harmonic channels will exhibit different order of phase shifts, the analysis shows that such phase offsets can be compensated by adjusting the phase of local oscillator (LO) at receiver end. Extending the framework of the Shannon theorem, an M-channel harmonic communication system is shown to reduce the minimum required signal-to-noise ratio (SNR) at the input of receiver by M-times. In addition, this new technique indicates that the power consumption of transmitter can be significantly reduced up to 66%. Through the analysis of channel capacity, the harmonic system is proved to outperform the single channel counterpart especially when SNR is low.

        ''Recent progress toward the use of spin torque oscillators in real                 electronics systems''  



Spin torque oscillator (STO) is a newly emerging device that can generate a radio frequency (RF) signal in microwave frequency range simply by injecting a DC current. It has many attractive features such as simple structure, nano-scale dimension, low power consumption and compatibility with semiconductor fabrication processes, thus is expected to bring significant benefits when used as a microwave signal source in RF integrated circuits.

Since the initial experimental demonstrations, many research groups have been working on developing a high performance STO1-5, and in fact made significant progresses during the last decade. Our research group within AIST is specialized in magnetic tunnel junction (MTJ) film stack, which shows much larger magnetoresistance (MR) effect compared with a conventional all metallic giant MR (GMR) film stack. Using the MTJ stack, we have fabricated various types of STOs as well as a phase locked loop (PLL) to achieve good enough performance for practical applications6-8.

In this talk, the basic principle of STO is first explained, then recent progresses for developing a high performance STO are reviewed with an emphasis put on research efforts within AIST. Lastly, future research directions to mature this device for the use in real commercial applications are discussed.

About the Speaker:

Shingo Tamaru received the Ph.D. degree from Electrical and Computer Engineering Department of Carnegie Mellon University (CMU) in Pittsburgh, USA, in 2005. He then joined Seagate Technology Pittsburgh research center as a research staff member, where he was first engaged in ferroelectric probe storage technology and next heat assisted magnetic recording technology projects. He moved back to CMU as a project scientist in 2009, where he studied spin wave physics and spin torque oscillator. He moved from the USA to Japan in 2012, and joined Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan, as an invited senior researcher. His research interests include high frequency spintronics, magnetization dynamics and magnetic recording technology. His current research efforts are focused on practical applications of spin torque oscillators, such as realization of a very small yet highly stable microwave generator or ultra-high sensitivity magnetic field sensor based on spin torque oscillator, next generation magnetic recording technology utilizing microwave magnetic fields generated by a spin torque oscillator (microwave assisted magnetic recording technology) and so on.
