摘　　要：FDTD方法已成为计算电磁学的一个重要发展方向。在时域有限差分法基本原理的基础上,通过建立二维TE波的FDTD表达式,实现了基于MATLAB的TE波传播仿真与吸收边界条件的验证。仿真结果表明:PML对TE波的传播具有良好的吸收效果。FDTD has become an important development direction in computational electromagnetic.Based on the basic principle of FDTD,through establishing the 2-D TE mode FDTD arithmetic expression,the spread of TE wave under the PML absorbing boundary conditons and verification based on MATLAB is implemented.Simulation result indicates that PML is effective in the spread of TE wave and MATLAB and can be used to test the result of programs.
