| 摘 要： | 以两层平面分层媒质为例,讨论了不同情况下空域格林函数的计算方法,指出了有耗平面分层媒质情况下传统方法的缺点,提出采用二维离散复像法(2D-DCIM)处理有耗平面分层媒质中的格林函数,并对积分路径做了相关要求,得到了同时包含场点纵坐标z和源点纵坐标z′及场源点横向距离ρ的格林函数的空域闭式表达式。所得结果与数值积分法的结果吻合良好,证实了该文方法的正确性。

| Abstract: | Using two layer media as example,this paper discusses the calculation methods of spatial Green's function in different situations,and points out the disadvantages of traditional methods when they are used in lossy planar layer media.Then two-dimensional discrete complex image method(2D-DCIM) is proposed to deal with the Green's function in lossy planar layered media,and the integral path is adjusted,then closed-form spatial Green's function is derived,which contains field point's vertical coordinate z,sourc... |
