| 摘 要： | 共形完全匹配层是一种有耗各向异性媒质组成的凸且光滑的壳体，其底面一般是PEC面或PMC面，但是PEC面或PMC面会对原散射场产生反射；为了减少底面反射，将CPML原有的PEC（或PMC）底面改为矢量ABC吸收边界，并给出了带矢量ABC底面的CPML泛函公式。通过数值算例证明，这种带矢量ABC底面的CPML边界不仅减少了底面反射，而且吸收效果好，计算精度高。

| Abstract: | Perfectly Matched Layers(PML) are the layers of electromagnetic wave absorbing elements designed for the mesh truncation of an open domain in a harmonic or modal analysis.It is an artificial anisotropic material that is transparent and heavily lossy to incoming electromagnetic waves.Conformal PML(CPML) is a convex and smooth shell region made up of lossy anisotropic medium.Generally,a CPML region is backed by a PEC boundary condition or a PMC boundary condition.But there are some reflections back into the c... |
