170GHz回旋管准光模式变换器的设计
Design of a quasi-optical mode converter for a 170 GHz gyrotron
摘要
Abstract
A high efficiency Denisov-type quasi-optical mode converter for a 170 GHzTE31,8mode gyrotron is pre?sented. The mode converter comprises a dimpled-wall launcher and a mirror system. Based on the coupled mode theory,the advanced launcher having two stages of perturbations is investigated. A mirror system of the converter is optimized and designed by using the vector diffraction theory. Simulation results show that the good Gaussian mode is converted from the circular waveguideTE31,8 mode and the mode conversion efficiency of a quasi-optical mode converter is 93. 7％.关键词
