摘要
将水平层状介质中的任意方向磁偶极子分解成水平磁偶极子(HMD)和垂直磁偶极子(VMD),给出了将VMD和HMD产生的波分解为电场矢量垂直于入射面的线形极化波(EV波)和平行于入射面的线形极化波(EP波)的方法.通过分别研究这两种波在各层介质中的反射和透射规律,导出确定各介质层中电磁波的递推公式,从而得到了任意介质层中电磁波的解析表达式.
By resolving a free oriented magnetic of HMD and VMD to EV and EP wave is given. By dipole to HMD and VMD, a method for resolving the wave studying the reflection and transmission of EV and EP wave on each layer,a kind of recurrence formula of electromagnetic wave in each layer is proved,and then an analytic expression for electromagnetic field of MD with Bessel function integral, which satisfies boundary condition of each layer, is obtained.
