處理反對稱結構電磁散射問題的廣義鏡像法
GENERALIZED IMAGE METHOD FOR DEALING WITH THE ELECTROMAGNETIC SCATTERING FROM ANTI-SYMMETRIC OBJECTS
-
摘要: 本文提出一種處理反對稱結構的電磁散射問題的廣義鏡像法,將它和數值方法相結合,可以大量節(jié)省求解散射場過程中所需要的計算機內存和計算時間。本文就二維問題對此進行了詳細討論,并給出了計算實例。

Abstract: The generalized image method (GIM) was presented to deal with the electromagnetic scattering from anti-symmetric objects. Combined with numerical methods, it can-make the required storage and CPU time to be greatly reduced. The method was thoroughly studied in two dimensional problems and some numerical examples were given. -
