Examination of long-distance high-power microwave power transmission system

Abstract

  Utilizing the phase-controlled magnetron technology, we examined a long-distance high-power microwave wireless power transmission system. We suggest constructing a phased array of high-power microwave output using the phase-controlled magnetrons. The phase-controlled magnetrons have completed which achieved within ± 1° phase accuracy, and high-efficiency power combining can be realized. The transmission beam control is performed from the injection signal which can avoid the loss due to the high-power phase shifter. In this paper, we designed a 12-kW power transmission system using sixteen 5.8-GHz band magnetrons and examined a high-power microwave power transmission system. We also conducted cost evaluations for actual experiments.
