用电场的体积积分方程处理了由大量磁芯组成的三维波导系统端面的平面波散射，并解析导出了TE波和TM波入射的扰动解的一阶项。远散射场几乎不依赖于入射波的偏振，其角度依赖关系被描述为入射场在岩心截面上的傅里叶变换。为了阐明散射模式与岩心排列的关系，给出了一些数值算例。
The scattering of a plane wave from the end-face of a three-dimensional waveguide system composed of a large number of cores is treated by the volume integral equation for the electric field and the first order term of a perturbation solution for TE and TM wave incidence is analytically derived. The far scattered field does not almost depend on the polarization of an incident wave and the angle dependence is described as the Fourier transform of the incident field in the cross section of cores. To clarify the dependence of the scattering pattern on the arrangement of cores some numerical examples are shown.
