on the efficiency of transmit / receive antenna efficiency and the efficiency of microwave rectifiers; its economy to rely on ponents used in the price band of microwave transmission systems and cable equipment for the parison, but also with specific parameters of the work are related. C oncern ing the economy and efficiency, but also for high-power microwave on the environment and the possible impact of health research, it is need to ensure the following aspects: (1) transmission of microwave energy density will not create a noticeable disturbance on the ionosphere; (2) it must be Et guarantee and will not to interfere with munication; (3) ground receiving stations can not have a negative effect on aircraft and other modes of transport anisms (such as birds, people, etc.).
