Reconfigurable intelligent surface with orientation-aware unit cells

Abstract

The present disclosure relates to a reconfigurable intelligent surface (RIS). A RIS is provided that can be conformed to a non-planar surface, the RIS including a plurality of RIS unit cells, a plurality of accelerometers, each accelerometer configured to detect accelerometer data for at least one of the RIS unit cells; and a controller configured to determine an operating condition of the RIS based on the detected accelerometer data of the RIS unit cells and to adjust one or more operational parameters based on the operating condition. Also provided is a method of operating such a RIS, wherein each RIS unit cell includes a dedicated accelerometer configured to detect the accelerometer data of the RIS unit cell.

Dependencies are inferred from the claim text.
