To verify the effect of artificial anisotropy parameters in one‐step leapfrog hybrid implicit‐explicit finite‐difference time‐domain (FDTD) method, we calculated several microwave components with different characteristics. Introduced auxiliary field variable can reduce the program difficulty and improve the computational efficiency without additional computational time and memory cost. Analyses of the numerical results are proved that the calculation time is reduced to about one‐sixth compared to the traditional FDTD method for the same example simulated. The memory cost and relative error are remained at a good level. The numerical experiments for microwave circuit and antenna have been well demonstrated the method available.

各向异性一步跃迁HIE-FDTD方法在微波电路和天线中的应用

为了验证人工各向异性参数在一步跃式混合隐式显式时域有限差分时域（FDTD）方法中的影响，我们计算了几种具有不同特性的微波分量。引入的辅助字段变量可以减少程序难度并提高计算效率，而不会增加计算时间和存储成本。数值结果分析证明，对于相同的示例，与传统的FDTD方法相比，计算时间减少了大约六分之一。存储器成本和相对误差保持在良好水平。微波电路和天线的数值实验已经很好地证明了可用的方法。
