Shattering the Fundamental Barriers in Realization of End-to-End Ultrahigh Data-Rate Transceivers: Direct (De-) Modulation in RF Domain
Speaker: Payam Heydari, Univ of California, Irvine
There is a widely held belief that going all digital is the pathway to design modern RF transceivers. This talk challenges this notion. It argues that when it comes to implementation of transceivers at ultra-high data rates going all the way up to 100 Gbps and above, the conventional architectures face some incredible challenges that are impossible to resolve. The talk will then present a solution to this fundamental barrier, namely, the new idea of realizing modulation and demodulation schemes in RF domain. Based on this new philosophy, a number of transmitters and receivers designed and fabricated in silicon technologies will be presented, as proof of concept.

The Future in Space: Connected, Small and Cooperative?
Speaker: Klaus Schilling, President, Center for Telematics, Würzburg, Germany
A paradigm change in spacecraft engineering can currently be observed: from traditional multi-functional, large spacecraft towards robust systems of networked, cooperating, distributed very small satellites. Similar trends emerged in computer systems since 1970, where the large mainframe computers were replaced by today’s smart phones, networked via Internet to form the basis for cloud computing. Thus inter-satellite links provide the basis exchange of information in the self-organizing small satellite formation. The deficits of miniaturization are to be compensated by advanced control and networked cooperation.
These principles will be illustrated by pico-satellite formation examples in the application areas Earth observation and telecommunication. Appropriate baseline distances between detectors on-board raise challenging communication and control requirements. Nevertheless, in combination with sensor data fusion innovative approaches for the “Internet of Things” via space result. In Earth observation, concrete examples under development at ZfT include “TOM – Telematics earth Observation Mission”, a 3 pico-satellite formation for photogrammetric observations. It is part of the international missions TIM (Telematics International Mission), where partners from 5 continents contribute CubeSats for 3D Earth observation. In the CloudCT mission, clouds are characterized by tomographic methods via 10 cooperating pico-satellites.
Klaus Schilling had in space industry responsibility in Earth observation and interplanetary satellites (such as HUYGENS to the Saturnian moon Titan and ROSETTA for exploration of comets, where adaptive control technologies assisted handling of uncertainties), before he was appointed professor and chair for Robotics and Telematics at University Würzburg. In parallel he is president of the research company „Center for Telematics (ZfT)“. His team built the first German pico-satellite UWE-1, launched 2005 to optimize Internet in space. He published more than 350 papers and received several awards, including the Walter-Reis-Award for Robotic Innovations 2008 (for research in mobile robotics) and 2012 (for medical robotics), as well as an Advanced Grant of the ERC 2012 for research on control of networked distributed satellite systems and an ERC Synergy Grant for CloudCT to improve climate models by observations from a formation of small satellites. He is full member of the International Academy of Astronautics and was Consulting Professor at Stanford University 2002-2006.
In international professional societies he served in IEEE as chair of "TC on Networked Robotics" and in IFAC (International Federation on Automatic Control) as Coordinating Chair for the area “Computers & Control” after having been TC chair for "Telematics: Control via Communication Networks" and for "Aerospace”.
Microwaving a Biological Cell Alive ‒ Broadband Label-free Noninvasive Electrical Characterization of a Live Cell
Speaker: James C. M. Hwang, Cornell University
Microwave is not just for cooking, smart cars, or mobile phones. We can take advantage of the wide electromagnetic spectrum to do wonderful things that are more vital to our lives. For example, microwave ablation of cancer tumor is already in wide use, and microwave remote monitoring of vital signs is becoming more important as the population ages. This talk will focus on a biomedical use of microwave at the single-cell level. At low power, microwave can readily penetrate a cell membrane to interrogate what is inside a cell, without cooking it or otherwise hurting it. It is currently the fastest, most compact, and least costly way to tell whether a cell is alive or dead. On the other hand, at higher power but lower frequency, the electromagnetic signal can interact strongly with the cell membrane to drill temporary holes of nanometer size. The nanopores allow drugs to diffuse into the cell and, based on the reaction of the cell, individualized medicine can be developed and drug development can be sped up in general. Conversely, the nanopores allow strands of DNA molecules to be pulled out of the cell without killing it, which can speed up genetic engineering. Lastly, by changing both the power and frequency of the signal, we can have either positive or negative dielectrophoresis effects, which we have used to coerce a live cell to the examination table of Dr. Microwave, then usher it out after examination. These interesting uses of microwave and the resulted fundamental knowledge about biological cells will be explored in the talk.

What is My Measurement Equipment Actually Doing? Implications for 5G, mmWave and Related Applications.
Speaker: Jon Martens, Anritsu
Current microwave and high frequency instrumentation perform many tasks behind the scenes, even more so in the mm-wave and high modulation rate regimes, and it is easy to lose track of how the equipment, the processing algorithms, the setup and the signals are interacting. By exploring the measurement mechanics within some common instruments under practical conditions, it may be easier to understand where sensitivities or anomalies might increase and how to mitigate them. Through a study of example architectures and measurements, including those in the 100+ GHz range and those with wide modulation bandwidths where linearity, dynamic range and other physical metrics are stressed even more, mechanisms and ideas for better measurements will be explored.
Jon Martens has been with Anritsu since 1995 where he is currently an Engineering Fellow. His research interests include measurement system architectures and pathologies, millimeter-wave circuit and system design, and a wide range of microwave measurement processes to include materials analysis, nonlinear and quasi-linear characterization, optical interactions and calibration.
He is the inventor or co-inventor on over 17 patents, has (co-)authored several book chapters and over 50 technical publications. Dr. Martens is a past chair of the MTT measurements technical subcommittee and is a past president of the measurements society ARFTG and is still active in both. He is a member of the technical program subcommittees for the International Microwave Symposium and ARFTG and is a former associate editor for the Transactions on Microwave Theory and Techniques.
