摘要

本文提出了一种用于te5,3模式回旋管的准光学模式变换器，该变换器由一个螺旋波纹发射器和几个曲面反射镜组成。应用几何光学近似和矢量衍射理论，编制了反射镜系统的数值模拟程序。仿真结果表明，该方法在窗口平面上的矢量高斯模态含量达到95%以上。实验测量结果与理论预测非常吻合。

A high-efficiency quasi-optical mode converter for a 94GHz TE5,3 mode gyrotron

A quasi-optical mode converter, consisting of a helically corrugated launcher and a few curved mirrors, for a TE5,3 mode gyrotron is proposed in this paper. Applying the geometric optics approximation and the vector diffraction theory, a numerical simulation code of the mirrors system is developed. Simulation results show that the vector Gaussian mode content in the window plane more than 95% has been achieved. Experimental measurements show close agreement with theoretical predictions.
