REALIZING PROGRAMMABLE WIRELESS ENVIROMENTS THROUGH SOFTWARE-CONTROLLED METASURFACES

摘要

A system for controlling an interaction of a surface with an impinging electromagnetic wave is provided. The system comprises a surface comprising a plurality of controllable elements, wherein each of the controllable elements is configured to adjust its electromagnetic behavior based on a control signal received by the controllable element, a sensing unit configured to detect a state of an environment of the surface and/or one or more wave attributes of an electromagnetic wave impinging on the surface, a control unit configured to determine, based on the detected state of the environment and/or the one or more wave attributes, a control state of the controllable elements, in which the electromagnetic behavior of the controllable elements is adjusted such that the surface interacts with the impinging electromagnetic wave in a predefined manner, and an adjusting unit configured to determine, based on the control state determined by the control unit, control signals to be transmitted to the controllable elements, which cause the controllable elements to adjust their electromagnetic behavior according to the control state, wherein the adjusting unit is further configured to transmit the control signals to the controllable elements.
