The Calculation for the Diffraction Field of a Steady-State Quasi-Optical Resonator

稳定型准光腔外衍射场的计算是实现准光功率合成与天线一体化设想的关键性问题。本文在A.L.Cullcn提出的准光腔复源点理论和L.B.Felsen提出的复射线理论基础上结合几何分析和计算,得到了E和H平面远区方向性图。本文的计算与实验结果基本吻合。

The calculation for the diffraction field of a steady-state quasi-optical resonator is a key problem to realize the integration of quasi-optical power combiner with antenna. In this paper, the diffraction field of a steady-state quasi-optical resonator has been calculated by combining complex source theory and complex ray theory with GTD. The far field patterns of diffraction field in E and H plane are given. These calculated results are verified by the experiment.
