摘要

本文讨论了用经典场论和算子理论求解重入型谐振腔的格林函数问题.首先讨论了经典场论中用H

的格林函数进行场匹配的方法

推导和讨论了H

的格林函数方程组、边界条件和格林函数的求解方法.这一方法只能用于回旋对称模式.为了解决耦合腔的问题需要高次模的格林函数

本文用算子理论求解了高次模的格林函数.这一格林函数对于零模与经典场论完全一致.本文也给出了高次模的格林函数、边界匹配方法和本征值的数值计算.这些工作为非轴对称耦合腔系统的分析和计算准备了必要的条件.

Abstract

The problems on solving resonant frequency of an entrant cavity by classical electromagnetic theory and operator theory are discussed.The classical method for boundary field matching by Green's function of H

is discussed firstly.The equation set for Green's function

the boundary conditions and method for solving Green's function are all given.This method can be only used for zero order mode.For higher order modes operator theory is used.The Green's functions of higher order modes

the method for boundary field matching and the calculation for eigenvalues of higher order modes are given.It is an essential condition for solving the problems of axially unsymmetrical coupled cavities system.
