Inagaki Mode Approach to Electromagnetic Scattering of Conducting Bodies at Interior Resonances
基于Inagaki模式方法分析导体内谐振特性

When either electric field integral equation or magnetic field integral equation is employed to analyze electromagnetic scattering of conducting bodies, at some discrete resonance frequencies, the solution of Method Of Moments(MOM) matrix will be nonunique or unstable. In this paper, a new effective method is presented to solve this problem. At the interior resonance frequencies, Inagaki mode method, based on electric field integral equation, is used to filter out resonance modes and obtain right parameters. The proposed method possesses the merits of clarity in concept and simplicity in computation. A good agreement is achieved between the calculated results and the published as well as the analytical results.
