摘要
首先介绍了电磁边界设置在电磁场计算中的重要意义和常用的四类边界条件的基本原理;其次对三维PML吸收边界条件进行了深入探讨;选取100MHz的平面波为激励源,分别采用四类边界条件,以典型长方体导体槽为分析模型进行电磁场模拟吸收的数值仿真;最后比较仿真结果得出了各种边界条件的应用范围。
In this paper, the importance of the electromagnetic border settings in the electromagnetic application and the theoretical foundation of four types of boundary conditions are introduced; focused on the three-dimensional PML absorption conditions conducted in-depth analysis; selected IOOMHZ incentive for the plane wave source and catch rectangular conductor slot as a model, in four categories of boundary conditions for the numerical simulation; compared the simulation results and studied those scope of application.
