Power Beaming Project Beam Hopper Reflector Test Results
Abstract
The Air Force Research Laboratory, Directed Energy Directorate (AFRL/RD) is developing a novel wireless power beaming concept to provide new capabilities for electrical power transmission. In the concept under development, 95 GHz millimeter wave (MMW)electromagnetic radiation is transmitted over long distance wirelessly, through the air, as a focused beam. The MMW radiation is then captured by a heat exchanger system which converts the MMW energy to heat in order to drive a Stirling-type heat engine and 60 Hz low-frequency Alternating Current (AC) generator, by heating the Stirling engine working fluid. The heat exchanger utilizes novel susceptor ceramics which heat due to dielectric loss mechanisms when the MMW beam is applied. So, through this concept a transmitted MMW beam produces standard-frequency AC power at a distance up to 1 km.
