Design of a Circular-Patch Reflectarray for Microwave Power Transfer and Communications in Space
2019 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2019This work presents the design and simulation of holographic reflectarrays made up of circular patches for wireless power transfer (WPT) in the Fresnel region. We simulate efficient focusing at 5.8 GHz for a 1.216m square reflectarray design at a focal distance of 10m.

Design of an RF Power Generator for Directional Radiation in Microwave Power Transfer System
2019 IEEE 13th International Conference on Power Electronics and Drive Systems (PEDS), 2019This paper presents a kind of radio frequency (RF) power generator with ability of directional radiation in microwave power transfer (MPT) system. This power generator uses quadrature modulation which can regulate amplitude and phase as a close loop.

Wireless power transfer by focusing microwaves
Wireless power transfer (WPT) promises to revolutionize energy distribution. Electromagnetic waves propagate freely through space, and can be used for long distances. It is advantageous to use microwaves since its wavelength reduces the size of the necessary components, while avoiding absorption losses in most media.openaire +1 more source
