Abstract

The derivation of the body‐of‐revolution finite‐difference–time‐domain (BOR‐FDTD) technique is presented and used to determine the return loss and radiation patterns of a corrugated horn. The perfectly matched layer (PML) absorbing boundary conditions are used for the computation. The source excitation is a sine‐modulated Gaussian pulse, spatially weighted with the cylindrical TE~11~ mode fields. The results for the return loss and radiation patterns are compared with those obtained using a commercial package based on a mode‐ matching/method‐of‐moments technique. The results show excellent agreement. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 33: 452–457, 2002; Published online in Wiley InterScience (www.interscience.wiley.com).
