摘要

本文分析了输电线在入射电磁场作用下的响应。提出了一种新的二维时域有限差分法，用于分析斜入射电磁波对无限散射物体的响应。推导了麦克斯韦方程、微分方程和PML吸收边界条件。采用一维时域有限差分法计算入射波的连接边界。给出了该方法的若干数值计算，并与传输线理论计算结果进行了比较，证明了该方法的正确性和优越性。

Study on infinite objects' scattering problems

The paper analyzes the response of power lines excited by an incident electromagnetic field. A new 2D FDTD method is proposed which analyzes the response of infinite scattering objects excited by electromagnetic waves at an oblique incidence. Maxwell's equations, differential equations and PML absorbing boundary conditions (ABC) are derived. The connecting boundary, where the incident wave is inducted, is computed by the 1D FDTD method. Several numerical calculations of this new FDTD method are provided and compared with the results of transmission line theory, proving the correctness and advantage of this new method.
