加載矩形波導(dǎo)中的并矢格林函數(shù)及其應(yīng)用
DYADIC GREEN S FUNCTION FOR LOADED RECTANGULAR WAVEGUIDE AND ITS APPLICATION
-
摘要: 本文用鏡像法推導(dǎo)出加載矩形波導(dǎo)中的并矢格林函數(shù)。在具體計(jì)算中,由于應(yīng)用積分變換以及將多重?zé)o窮求和化為單一無(wú)窮和,極大地簡(jiǎn)化了計(jì)算,節(jié)省了計(jì)算時(shí)間。作為并矢格林函數(shù)應(yīng)用的例子,給出了位于加載波導(dǎo)寬邊上的金屬球散射場(chǎng)的矩量解.計(jì)算結(jié)果與實(shí)驗(yàn)和文獻(xiàn)的結(jié)果吻合很好。這種方法還能推廣到其它波導(dǎo)。

Abstract: This paper presents a method to derive the dyadic Green s function of a loaded rectangular waveguide by image method. In the calculation of the DGF, it is simplified by using the integral transformation and replacing the multi-infinite summation with a single one. As an example of the DGF s application, the scattering field calculation of a metal sphere resting on the broad wall of the loaded rectangular waveguide is given by mo ney ethod. Results of calculations agree well with both data of experiments and those published. -
