A metasurface solution for the estimation of direction of arrival of electromagnetic waves is presented. The metasurface, which is programmable, is used as a reflector with an adjustable pointing direction to scan the azimuth plane for sensing and reflecting incoming waves to a focal point, thereby estimating the incident direction. Furthermore, in order to achieve rapid and precise direction of arrival (DOA) estimation, a processing layer based on a pre-trained multilayer neural network is exploited to interpret variation in recorded power levels.
