Reconfigurable Intelligent Surfaces of Communications and Radars
In recent years, reconfigurable intelligent surfaces (RISs) have shown promising
abilities to control and manipulate electromagnetic (EM) waves through modified surface
boundary conditions. These surfaces are electrically thin and comprise an array of spatially
varying sub-wavelength scattering elements (or meta-atoms). Through careful engineering
of each meta-atom, RISs can transform an incident EM wave into an arbitrarily tailored
transmitted or reflected wavefront. Recent developments in RISs have opened exciting new
opportunities in antenna design, as well as communications and radar systems. RISs - wherein
meta-atoms are embedded with active components - lead to the development of low-cost,
lightweight, and compact systems that can produce programmable radiation patterns,
jointly perform multi-function communications, and enable advanced radars for next-generation
military platforms. This talk will introduce RISs and their various applications in
designing simplified communications and radar systems, wherein the RF aperture and
transceiver are integrated within the RIS. For example, dynamic reconfiguration of the RIS
aperture in a wireless communications transmitter facilitates beam steering, frequency
agility, and phase modulation without conventional front-end devices such as phase-shifters,
mixers, and switches. We will present our recent work on reconfigurable RIS control, RIS-enabled
direct signal modulation, and deep learning-based RIS design. Finally, we will
present deploying RIS as a reflector in the wireless channel for aiding non-line-of-sight radar
and joint radar-communications.

Reconfigurable Intelligent Surfaces of Communications and Radars
Biography:
Kumar Vijay Mishra (S’08-M’15-SM’18) obtained a Ph.D. in electrical engineering and M.S. in
mathematics from The University of Iowa in 2015, and M.S. in electrical engineering from
Colorado State University in 2012, while working on NASA’s Global Precipitation Mission
Ground Validation (GPM-GV) weather radars. He received his B. Tech. summa cum
laude (Gold Medal, Honors) in electronics and communication engineering from the
National Institute of Technology, Hamirpur (NITH), India in 2003. He is currently Senior Fellow
at the United States Army Research Laboratory (ARL), Adelphi; Technical Adviser to
Singapore-based automotive radar start-up Hertzwell and Boston-based imaging radar
startup Aura Intelligent Systems; and honorary Research Fellow at SnT - Interdisciplinary
Centre for Security, Reliability and Trust, University of Luxembourg. Previously, he had research
appointments at Electronics and Radar Development Establishment (LRDE), Defence
Research and Development Organization (DRDO) Bengaluru; IIHR - Hydroscience &
Engineering, Iowa City, IA; Mitsubishi Electric Research Labs, Cambridge, MA; Qualcomm,
San Jose; and Technion - Israel Institute of Technology.
Dr. Mishra is the Distinguished Lecturer of the IEEE Communications Society (2023-2024), IEEE
Aerospace and Electronic Systems Society (AESS) (2023-2024), IEEE Vehicular Technology
Society (2023-2024), and IEEE Future Networks Initiative (2022). He is the recipient of the IET
Premium Best Paper Prize (2021), U. S. National Academies Harry Diamond Distinguished
Fellowship (2018-2021), American Geophysical Union Editors' Citation for Excellence (2019),
Royal Meteorological Society Quarterly Journal Editor's Prize (2017), Viterbi Postdoctoral
Fellowship (2015, 2016), Lady Davis Postdoctoral Fellowship (2017), DRDO LRDE Scientist of the
Year Award (2006), NITH Director’s Gold Medal (2003), and NITH Best Student Award (2003).
He has received Best Paper Awards at IEEE MLSP 2019 and IEEE ACES Symposium 2019.
Dr. Mishra is Chair (2023-present) of the Synthetic Apertures Technical Working Group of the
IEEE Signal Processing Society (SPS) and Vice-Chair (2021-present) of the IEEE Synthetic
Aperture Standards Committee, which is the first SPS standards committee. He is the Vice
Chair (2021-2023) and Chair-designate (2023-2026) of the International Union of Radio
Science (URSI) Commission C. He has been an elected member of three technical
committees of IEEE SPS: SPCOM, SAM, and ASPS; and IEEE AESS Radar Systems Panel. Since
2020, he has been Associate Editor of IEEE Transactions on Aerospace and Electronic Systems,
where he was awarded Outstanding Editor recognition in 2021. He has been a lead/guest
editor of several special issues in journals such as IEEE Signal Processing Magazine, IEEE Journal
of Selected Topics in Signal Processing, and IEEE Journal on Selected Areas in
Communications. He is the lead co-editor of three upcoming books on radar: Signal
Processing for Joint Radar-Communications (Wiley-IEEE Press), Next-Generation Cognitive
Radar Systems (IET Press Radar, Electromagnetics & Signal Processing Technologies Series),
and Advances in Weather Radar Volumes 1, 2 & 3 (IET Press Radar, Electromagnetics & Signal
Processing Technologies Series). His research interests include radar systems, signal
processing, remote sensing, and electromagnetics.
