Inagaki Mode Approach to Electromagnetic Scattering of Conducting Bodies at Interior Resonances

摘要

摘要: 當應(yīng)用電場積分方程或磁場積分方程對導(dǎo)體散射特性進行矩量法分析時，在某些離散的頻率點即內(nèi)諧振點上，常常出現(xiàn)解的不穩(wěn)定或不唯一情況。為了解決這一問題，該文提出了一種新型的消除內(nèi)諧振的方法。這種方法基于電場積分方程，利用Inagaki模性質(zhì)有效地去除了諧振模式，獲得內(nèi)諧振條件下正確的導(dǎo)體散射特性。該方法具有概念清晰和計算簡便等優(yōu)點。計算結(jié)果與公開發(fā)表的文獻結(jié)果以及解析解相比，一致性良好。

Abstract: 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.
