Lossless microwave devices using SWP

Magnetron and other microwave amplifiers and oscillator are very useful in generating high power at high microwave frequencies. However they all suffer loss of efficiency and performance. This occurs due to back heating electrons and standing waves in magnetron and TWT amplifiers respectively. This paper sujjegsts a hypothetical method of reducing destructive effects in these devices with the phase shifting property of Spatial walk off polarizer. The spatial walk off polarizer or SWP has a property of reducing EM wave with a phase other than that of input wave. Thus using a SWP in close proximity of a cathode can significantly reduce the effects of back heating and standing wave ratio and thus increase the efficiency, life and performance of numerous microwave devices. In this paper author aims to explain the same for the case of magnetron. If hypothesis come out to be valid it can easily be extended to other microwave devices.
