Abstract: Disclosed is an apparatus and method for wirelessly transmitting power to power receivers from a power transmitter. The present disclosure provides a rational search procedure for locations of the power receivers, and provides a function of simultaneously charging multiple receivers using microwave multi-focusing. The wireless power transmission method performed by a power transmitter includes determining angular coordinates of the power transmitter in relation to a position of at least one power receiver; determining a distance between the at least one power receiver and the power transmitter based on the determined angular coordinates by using a focused microwave field; determining a location of the at least one power receiver based on the determined angular coordinates and the distance; and wirelessly transmitting power by focusing the microwave field to the determined location of the at least one power receiver.

Abstract: The present disclosure relates to radio engineering, and more specifically to high-frequency (HF) signal transmission/reception devices based on photoconductive switching elements. An HF signal transmission/reception device comprises a signal electrode with matching elements disposed along an edge thereof; a ground electrode, a dielectric layer between the signal electrode and the ground electrode, photoconductive elements (PE) each electrically connected to the signal electrode and the ground electrode and arranged in a grid, an excitation signal feed point, and load elements electrically connected to the matching elements. The photoconductive elements each have a switched-off state in the absence of a control light flux and a switched-on state in the presence of a control light flux, The switched-on photoconductive elements form a reflection profile of the signal supplied from the excitation signal feed point. The distance between adjacent photoconductive elements is less than half the wavelength of the excitation signal.
