Abstract
A power transmitting method of a wireless communication system includes a metasurface. The method includes transmitting power of a power supply device to a target device through the metasurface comprising N cells, where N is an integer; estimating, by the metasurface, a channel between the metasurface and the target device based on the power received by the target device and a property matrix with a magnitude of (N+1)×(N+1); adjusting, by the metasurface, a phase of each cell of the N cells based on the estimated channel; and reflecting, by the metasurface, the power transmitted from the power supply device to the target device using the adjusted phase of each cell of the N cells. The property matrix includes information indicating whether each cell of the N cells is turned on and information about a bias value of the wireless communication system.
