Abstract
The technology described herein is directed towards remotely controlling the direction of a beam reflected from a reconfigurable intelligent surface arranged with a two-dimensional array of unit cells. By controlling a variable tuning device (e.g., varactor diodes) per unit cell, a microcontroller can distinctively adjust the phase of each unit cell, which can be the same phase per column of elements. In one implementation, the reconfigurable intelligent surface is reconfigured to change its beam reflection direction upon receiving a remote control signal (e.g., a five-bit digital code through infrared). The code can be mapped to predefined phase profile data of a group of phase profile data options, that is, to a set of varactor voltages selected from available varactor voltage configurations, which is then applied to the varactors. In this way, the reflected beam can be controlled to reflect an electromagnetic wave (e.g., mmWave) in a specified direction.
