摘要：
In this paper we discuss the use of perfectly matched layers (PMLs) for the termination of conducting media in the body of revolution finite difference time domain (BOR-FDTD) algorithm. This type of termination enables us, to accurately and efficiently model long conductors possessing rotational symmetry. The formulation is validated by investigating the propagation characteristics of two practical guiding wave structures, viz., a coaxial cable (RG-142) and a circular waveguide operating in the TE11 mode. Both the conductors as well as dielectrics are extended into the PML region in order to simulate infinitely long guides. Copyright (c) 2006 John Wiley & Sons, Ltd.
