Abstract
Provided is a method for transmitting power in wireless communication using reconfigurable intelligent reflecting surfaces (RIS) of an electronic device, which includes: determining a value of a reflection coefficient of each unit cell or tile by scanning each tile of a reconfigurable intelligent reflecting surface (RIS) by a signal radiated through a transmitter; sending a beam to the reconfigurable intelligent reflecting surface (RIS) by controlling the transmitter; and multi-focusing an electromagnetic wave signal incident on the reconfigurable intelligent reflecting surface (RIS) on a plurality of receivers by setting an on/off state in each unit cell of the reconfigurable intelligent reflecting surface (RIS) based on the determined control parameter value, in which the tile is a partial array of the RIS having the same size, and supports far-field communication for the plurality of receivers.
