DL Talk: Reconfigurable Intelligent Surfaces for Communications and Radars (HYBRID)
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.
