摘要
将任意截面二维散射体的积分方程法推广到含有有源分子的任意形状单粒子的弹性和非弹性散射分析,同时考虑了场点与源点相同时散射场的修正问题。根据电磁场的本征函数展开,得到了粒子内外的弹性和非弹性场的矢量球波函数展开式,展开系数通过解一组耦合线性方程可得。
The integral equation method for analysing the scattering fromtwo-dimensional objects of arbitrary cross section is extended to analyze the elastic andinelastic scattering from an arbitrary body embedded with active molecules,and the correc-tion of field inside the body is taken into account as the field point and source point areat the same position.The EM fields in various regions are expanded in terms of vectorspherical wave functions,and the expansion coefficients can be solved from a set of coup-led linear equations.The numerical results show that the integral equation method is accu-rate enough as the dielectric constant of the body is near to that of the surrounding me-dium and/or the maximum linear dimension of the body is near to the wavelength of theincident EM wave.
