有限差分法在方同轴线仿真中的应用

Application of FDM Method in the Numerical Simulation of Square Coaxial Lines

以电磁理论和有限差分法为基础,对方同轴线结构进行差分数字化,并编写计算机程序进行仿真计算。把计算结果与成熟的CST软件的仿真结果进行对比,验证了计算结果的正确性。本方法可推广到其它非规则电磁结构的计算。

Based on the electromagnetic theory and the finite difference method, difference digitization was conducted to investigate square coaxial line structure, and the computer program was designed to carry out the simulation computation. By comparing the simulated result with the result calculated by the mature software CST, it was found that the result obtained was accurate. This method can be used to other computation with non-regular electromagnetism structure as well.
