导体条带与周期粗糙面对电磁波的复合散射 THE COMPOSITE SCATTERING OF ELECTROMAGNETIC WAVES BY THE CONDUCTING STRIP AND PERIODIC ROUGH SURFACE 朱国强 Zhu Guoqiang 1 first-author 杨河林 Yang Heling 1 武汉大学电子信息学学院 武汉大学电子信息学学院 College of Electronic Information, Wuhan University College of Electronic Information, Wuhan University 建立了导体条带与正弦型周期粗糙面的复合散射模型，用感应电流的谱域积分表示导体条带的初级散射场，用物理光学方法计算周期粗糙面的次级散射场，所得复合散射解具有清晰的物理图像 A composite electromagnetic wave scattering model of the conducting strip and sinusoidal rough surface is established in this paper. The primary scattering field of the conducting strip is represented with a spectrum integral of the induced currents. The secondary scattering field of the periodic rough surface is calculated by using the Physic Optics （PO）. The composite scattering solution of the strip and rough surface has the clearly physical view. 目标与粗糙面 相互作用 电磁波散射 target and rough surface interaction electromagnetic wave scattering O441.4 国家自然科学基金(61672102) 1999-01-01 2021-04-01 1
