Design and simulation of quasi-optical mode generator for a W-band gyrotron

摘要

In this paper, a W-band rotating TE62 mode is achieved by means of a mode generator in order to test quasi-optical mode converters for gyrotrons. The generator consists of two mirrors and a coaxial cavity with a perforated outer wall. The simulation results of an electromagnetic analyses software show that the mode purity is up to 96.5%.
