Electronic device comprising a metasurface

An electronic device adapted to receive and process an electromagnetic radiation, such as a radio frequency signal from a wireless communication system, the electronic device comprising:

• a metasurface for intercepting the electromagnetic radiation, the metasurface comprising a plurality of active elements for sensing at least one parameter of the electromagnetic radiation as it is actually received at the electronic device, wherein the active elements of said plurality of active elements are controllable to implement a plurality of configurations of the metasurface each one corresponding to a radiation pattern with which the electromagnetic radiation is passed through the metasurface, and
• processing circuitry communicably coupled to the metasurface, wherein the processing circuitry is configured to iteratively:
• receive the sensed at least one parameter from the metasurface;
• identify, based on the at least one parameter of the electromagnetic radiation, an optimized configuration, among the plurality of configurations, that optimizes electromagnetic radiation reception at the electronic device, and
• control the active elements to implement the optimized configuration,
• wherein the metasurface acts as an antenna of the electronic device and wherein the optimized configuration implemented by the active elements allows optimizing electromagnetic radiation reception at the electronic device through the metasurface,
• wherein the processing circuitry is configured to control the active elements according to space-time coding, whereby the metasurface is configured to manipulate the electromagnetic radiation in both space and frequency domains by the processing circuitry controlling a reflection coefficient of the metasurface with discrete phase or amplitude states by applying control voltages to the active elements.
