摘　　要：推导了电磁场的时域有限差分法(FDTD)公式,分析了稳定性和边界条件,编程实现了相应的计算程序。采用FDTD方法模拟电磁波电场和磁场的运动规律,直观地呈现电磁波在均匀有耗媒质中平面电磁波传播瞬态特性。均匀有耗媒质中平面电磁波传播瞬态特性的研究是进一步研究多层有耗媒质中电磁波传播特性的基础。Electromagnetic field is deduced from the formula of finite difference time domain(FDTD) method(FDTD) stability and boundary condition are analyzed,the corresponding calculation program is realized.FDTD method is used to simulate the electromagnetic wave motion law of electric field and magnetic field,which can visually presented plane electromagnetic wave propagation transient characteristics in uniform lossy medium.Research of the transient characteristics of plane electromagnetic wave propagation in uniform lossy medium is the foundation for further studies in multilayer the lossy medium.
