摘要: 從電介質(zhì)散射的積分方程出發(fā),應(yīng)用本征函數(shù)展開法獲得了有源分子均勻分布的任意形狀介質(zhì)顆粒的彈性和相干非彈性散射計算公式。對于任意形狀顆粒的彈性散射問題,本文的計算公式與以前文獻中所建立的相應(yīng)計算公式完全相同,從而說明本文的計算公式不受弱散射條件的限制。此外,本文還給出了旋轉(zhuǎn)橢球形顆粒的相干非彈性散射問題的數(shù)值結(jié)果。

Abstract: Formulas for the elastic and coherent inelastic scattering be an arbitrary body uniformly filled with active molecules are presentd with the method of eigenfunction expansion in the integral equation for scattering by dielectric body Agreement between the formulas obtained for the elastic scattering by an arbitrary body and those in the previous literatures illustrates the formulas here are not restricted tc the situation of weak scatterring. Some numerical results for the coherent inelastic scattering by an ellipsoid uniformly filled with active mole- cules are given here. -
