摘　　要：对PML吸收边界条件进行了详细的讨论 ,给出了PML中Maxwell方程差分格式的推导方法。用典型的计算实例验证了通用程序的正确性 ,并将其应用于微带天线的具体计算中。该方法为FDTD模拟复杂电磁结构提供了方便 ,拓宽了其应用范围。The perfectly matched layer absorption boundary condition is discussed, especially for the method to get difference equation from differential equation. The correctness of the common used procedure is proved by a typical example. It is then applied in the calculation of a microstrip antenna. The PML makes convenient in the application of FDTD to the complex electromagnetic structures. So it extends the application area of FDTD.
