摘要

提出了截断超材料时域有限差分(FDTD)网格的简单有效的完美匹配层(PML)公式。这些公式是基于将z变换理论纳入FDTD算法来模拟超材料的频率依赖特性。通过一维超材料域的数值算例验证了所提公式的正确性。

Z-transform PML algorithm for truncating metamaterial FDTD domains

Efficient and simple formulations of the Perfectly Matched Layer (PML) are presented for truncating metamaterial Finite Difference Time Domain (FDTD) grids. The formulations are based on incorporating the Z-transform theory into the FDTD algorithm to model the frequency dependence property of the metamaterials. Numerical example carried out in one dimensional metamaterial domain is included to validate the proposed formulations.
