Systems and methods for detecting angle of arrival on a hybrid reconfigurable intelligent surface using intensity only data

Abstract

A system for detecting angle of arrival comprises an array of metamaterial or resonant elements that share a dielectric substrate and a metallic ground layer, wherein each of the metamaterial or resonant elements includes a switchable component; an opening in the ground layer configured to couple an incident wave signal; and a waveguide below the ground layer configured to guide the coupled signal to a receiving circuit including an intensity or power meter. A method for detecting angle of arrival comprises providing the system as described above; coupling an incident wave signal to the shared substrate; guiding the coupled signal from the shared substrate to the receiving circuit via the waveguide; measuring the coupled signal via intensity or power meter of the receiving circuit; and calculating an angle of arrival based on the measured intensity or power.
