The microwave power is transmitted through space in a narrow beam for capture and rectification at the receiving point. The microwave energy generator devices embodied in the invention are of the crossed field amplifier type having a very high efficiency and extremely long life through the use of a cold cathode secondary emitting electron source. The microwave generated power is transmitted through slotted waveguide radiator arrays with the phase of the energy monitored and corrections are made by phase shifting devices where necessary. | |
