Experimental analysis of RF based multi-plane-diffraction with over-the-air active cellular signal measurements

Abstract

Wi-Fi signal interference based radar structures and high spatial efficiency modulator designs utilizing the quantum properties of light with multi-plane-diffraction (MPD) design have been recently introduced. In this study, experimental studies were performed in a full anechoic chamber for wireless RF active cellular channels, inspired by the advantages of the MPD systems. Differences between free space propagation, single-plane and MP diffraction architectures are observed with experimental studies for different diffraction geometries by analyzing interference patterns. The results obtained in this study will form the basis for next generation sensor designs utilizing direct cellular signal interference and RF modulators exploiting the high spatial efficiency of MPD.
