本文运用矩量法结合复镜象理论,计算了有耗地面上方理想导电圆柱体表面上的感应电流和散射场,得到了直接在谱域中求解相符的结果。 In this paper, by using the method of moment and the theory of complex imagery, the induced current and the scattering field are calculated on the surface of ideal conducting cylinder above the dissipative ground. The corresponding results obtained directly in the spectral domain are obtained.
