对回旋管内置准光模式变换器进行了理论研究和数值模拟。基于几何光学理论和矢量绕射理论，编制了模拟电磁场行为的分析和优化程序，采用 Vlasov 辐射器和准光反射器实现了线极化准高斯模 HE11。结果表明：在一级反射镜下的转换效率为88.3%，增加反射镜级数会降低转换效率。%The theory and numerical simulation of quasi-optical mode converter inside the gyrotron is studied. The analysis and optimization code for the converter is developed based on the theory of geometry optics and vector diffraction to simulate the behavior of electromagnetic field, and linearly polarized quasi-Gaussian mode HE11 output is achieved by using a Vlasov radiator and a quasi-optical reflector. Experimental results suggest that, under one reflector, the power conversion efficiency is 88.3%, which will be reduced while the mirror series increases.
