Electron beam antenna microwave generation device

摘要

A high energy level arrangement for generating microwave frequency electromagnetic energy from a DC power source by way of a high energy level electron beam coupled into an output waveguide member and serving therein as an antenna source of energy for the waveguide member. The electron beam is preferably spatially and timewise modulated with sinusoids to improve conversion efficiency to dominant mode waveguide energy. The disclosure includes several embodiments including a waveform splicing arrangement and plural electron gun embodiments and discloses quantitative efficiency and operating voltage level data. Use of the invention in weaponry, radar, deep space communication and other high radio frequency level energy applications is also disclosed.
