Implications of the Reciprocity Theorem for Reconfigurable Intelligent Surfaces
Uday K Khankhoje, Debidas Kundu
Reciprocity between a transmitter and receiver is a foundational requirement in wireless communications. A few recent works have suggested that reciprocity is broken under reflecti…
A Miniaturized Broadband 1-Bit Coding Reconfigurable Intelligent Surface for NLOS UE Localization and Uplink Communication
Khagendra Joshi, Deepak Kumar Sahoo, Kamalesh Kumar K +3
In this paper, a broadband 1-bit coding metasurface-based reconfigurable intelligent surface (RIS) is presented. The unit cell of the metasurface consists of a wide dipole modified…
Radar Cross Section Characterization of Quantized Reconfigurable Intelligent Surfaces
Kainat Yasmeen, Shobha Sundar Ram, Debidas Kundu
We present a radar sensing framework based on a low-complexity, quantized reconfigurable intelligent surface (RIS) that enables programmable manipulation of electromagnetic wavefro…
Radar Sensing using Dual-Beam Reconfigurable Intelligent Surface
Kainat Yasmeen, Shobha Sundar Ram, Debidas Kundu
Around-the-corner radar sensing offers an opportunity for the radar to exploit multipath scattering along walls to detect targets beyond blockages. However, the radar detection per…
Around-the-corner Radar Sensing Using Reconfigurable Intelligent Surface
Kainat Yasmeen, Debidas Kundu, Shobha Sundar Ram
Around-the-corner radar (ACR) sensing of targets in non-line-of-sight (NLOS) conditions has been explored for security and surveillance applications and look-ahead warning systems…
