Abstract

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 TE~11~ mode. Both the conductors as well as dielectrics are extended into the PML region in order to simulate infinitely long guides. Copyright © 2006 John Wiley & Sons, Ltd.

## Abstract In this paper, we present a far‐field pattern calculation technique in the body‐of‐revolution finite‐difference time‐domain (BOR–FDTD) method. Because the BOR–FDTD solves two‐ and half‐dimensional problems, it has different features from the three‐dimensional FDTD method in the far‐fiel

## Abstract In this paper we use the body of revolution (BOR) version of the finite difference time domain method to analyze axially‐symmetric dielectric waveguides including optical fibers. Because the BOR technique is two‐dimensional in nature, it is an efficient tool for analyzing the modes in o
