Beam Steering Design for MW-Level Microwave Power Transmission in SSPS Demonstration

According to the space solar power satellite development strategies in China, a mega-watt (MW)-level SSPS on geostationary Earth orbit (GEO) demonstration will be carried out after 2030. Microwave power beam steering must be considered for the demonstration. Beam steering methods are reviewed for microwave power transmission applications. Then beam steering requirements are investigated for MW-level SSPS demonstration. Beam steering technology is proposed for the demonstration with consideration of MW-level microwave power transmitting subsystem design.
