Programmable Electromagnetic Surfaces with Spatio-temporal and Orbital-Angular Mode Synthesis of Ter
Abstract
1. Abstract: This proposal seeks support for a high bandwidth and ultra-high speed arbitrary waveform generator (Keysight M8196A, 3,0 GHz bandwidth, 92 GS/s), and a real-time 70 GHz and 256 GS/s real-time oscilloscope (Keysight UXR0702A) to allow research into re,volutionary programmable electromagnetic surfaces operating at frequencies above 100 GHza spectrum that can support jammer-tolerant, wireless communication, high-resolution radar, sensing and imaging. In this proposal, we take this one step further into programmab,le electromagnetic surfaces that can adapt with ultra-wide bandwidths (>30 GHz), but also has the ability to create in a reconfigura,ble fashion 1) Orbital Angular Mode synthesis, 2) Spatio-temporal field synthesis for physical layer security, and 3) Surface topolo,gy reconfiguration exploiting origami surfaces and active EM tiles. Through both shape control of the EM surface with origami actuat,ions, and electronic control of the fields, we will theoretically and experimentally investigate the,ve a transformative impact on a broad range of applications of interest to DOD including secure, jammer-tolerant, communication with, extreme bandwidth, data rates (>100 Gb/s), and high-resolution sensing, radar and imaging, contraband and explosive detection among, others. This crosscut approach is expected to enable a new direction for programmable broadband sensing, communication and imaging, systems that are compact, low-cost, scalable, and efficient.mmWave/THz Comm/Sensing Measurements: The ultra high-speed arbitrary wa,veform generator (30 GHz bandwidth, 92 GS/s) and real-time 70 GHz oscilloscope will enable extensive measurements of the systems pro,posed here that will be done in collaboration with the current existing DOD programs. In particular, this will be central to the cur,rent ONR research program on Large-scale Time-modulated mm-Wave Arrays for Dynamically Reconfigurable Spatial Mode Multiplexing in,ireless links (Nature Electronics21) and twisted wave generation. The instrumentation will also be central to the ongoing MURI proj,ect on 4D Electromagnetic Origami for programmable electromagnetic surfaces on conformal origami surfaces, sensors and metasurface,s (Nature Electronics18, Nature Comm19, Nature Electronics20). The instrumentation will be also critical to an expected start of,a new ARO program on Chip-scale Programmable Terahertz Surfaces through Inverse Design. Specifically, the proposed instrumentation, will allow us to push the frontiers of performance in both secure communication and sensing to a new dimension across frequencies,,bandwidths that is expected to address fundamental research questions and open up new applications in security, jammer -tolerant com,munication, and ultra high-resolution sensing.Instrumentation: Arbitrary waveform generator andreal-time oscilloscope (total: $813,5,11).Quantum Information Processing and Spectroscopy In addition, this instrumentation will also add to the capability of high-freque,ncy measurement facilities in Princeton Electrical and Computer Engineering to enable new modalities in quantum information processi,ng with studying electron spin resonances and superconducting circuits by allowing them to probe such properties at higher frequenci,es and higher magnetic fields. Training: Overall, the proposed system will allow training of graduate and undergraduate students in,the state-of-the-art research in RF-THz integrated electronics, electromagnetics and quantum science and encourage a generation of y,oung students to take up challenging problems beneficial to the DOD and society in general.
