提出了一种基于拉伸坐标系的高阶完全匹配层（PML），以有效地衰减传播波和倏逝波。新的PML具有多个极点，而常规的PML只有一个极点。的实施也来自和结果被证明是优于那些经常PML和最近提出的复频移（CFS）PAIL的计算成本的一个微不足道的增加。
A higher-order perfectly matched layer (PML) is proposed based on stretched coordinates to effectively attenuate both propagating and evanescent waves. The new PML has multiple poles in contrast to the regular PML with a single pole. The implementation is also derived and results are shown to be better than those of the regular PML and the recently proposed complex-frequency shifted (CFS) PAIL with an insignificant increase in the computational cost.
