Microwave power transmission technology, which is a sub-discipline of the wireless power transmission technology, aims to transmit electrical power without using wires/cables in the microwave frequency band. The retro-reflective beamforming technique has the potential to enable efficient and safe microwave power transmission, as it includes the following two technical elements. First, a directional microwave beam is generated as the carrier of wireless power. Second, the microwave power beam could be steered in real time toward mobile wireless power receiver(s). This book offers a comprehensive narrative of retro-reflective beamforming in the context of microwave power transmission.
