Abstract
The technology of the energy transmission using microwave is very useful in space as well as on the ground. We are preparing a rocket experiment (METS: Microwave Energy Transmission in Space) and its preparatory airplane experiment called MILAX (Microwave Lifted Aircraft eXperiment) in the International Space Year. The objectives of the METS are to verify a newly developed microwave energy transmission system in space and to study nonlinear effects of the microwave energy beam in the space plasma environment. We will also perform a ground-based energy transmission test of the developed system by using a small airplane as a target before the launch. The transmission test in the radio anechoic chamber showed that the transmission system developed for the MILAX can transmit enough power and accurately control the microwave beam.
