摘要

本文采用有限差分时域（FDTD）技术，对平面电磁波照射下的移动介质界面和介质板进行了数值研究。在 FDTD 时间环内，通过在特定时间移动结构的位置来获得运动。在时域和频域中，研究了正常入射时不同速度下的透射波和反射波。模拟的透射系数、反射系数和多普勒效应与文献中的闭式方程进行了比较。此外，还研究了菲涅尔阻力的影响。

Numerical Study of a Moving Dielectric Slab Illuminated by a Plane Wave With the Inclusion of Fresnel Drag

A numerical investigation of moving dielectric interface and dielectric slab illuminated by plane electromagnetic waves, using the finite-difference time-domain (FDTD) technique, is presented. Within the FDTD time loop, motions are obtained by shifting the locations of structures at particular times. The transmitted and reflected waves are studied, at normal incidence, for different speeds, in time and frequency domains. The simulated transmission coefficients, reflection coefficients, and Doppler effects are compared with closed-form equations that agree with the literature. Furthermore, the effect of the Fresnel drag is studied.
