    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 TE11 made 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. (C) 2002 Wiley Periodicals, Inc.
