用多极理论分析轴对称介质加载微波谐振腔
Multipole theory analysis of axisymmetrically loaded cavities
摘要
Abstract
A new approach, the multipole theory(MT) method, is presented for determining the resonant frequencies in axisymmetrically loaded cavities. The inhomogeneous field domain of loaded cavity is decomposed as a combination of several simple homogeneous regions, and the solution of the governing partial differential equation is represented by the generalized MT formula. Representative computational examples, including spherical cavity loaded with an eccentric dielectric sphere, cylindrical cavity and rectangular cavity loaded with dielectric rods, are given to validate the theory and to demonstrate the degree of its efficiency.关键词
