## 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 s

✦ Synopsis
In this article the numerical method for extracting diffraction coefficients of wedge structures is extended to calculate diffraction coefficients of wedges with the corrugated surfaces for which no closedform expressions exist. Extensi¨e numerical results are gi¨en, and they may be useful in design and engineering applications. We also pro¨ide some assessment of the diffraction coefficients of artificially soft surfaces deri¨ed more recently.

An alternati¨e technique that combines the matrix pencil ( ) MP method and the GTD-based model is presented to estimate scattering center parameters including frequency dependence, down range, and amplitude from computed and measured scattering field data. The technique does not employ the time-cons
## Abstract A numerical approach for transition problems in optical waveguides is presented, with the use of the Fourier‐series expansion method combined with the absorbing boundary condition by a perfectly matched layer (PML). The optical propagation along a transition is described by a simple mat
## Abstract The symmetrical condensed‐node TLM method is used for the analysis of microstrip lines with substrates of arbitrary varying thickness. This numerical technique has been efficiently used for the computation of the propagation constant and the characteristic impedance of this structure. M
In this paper the well-known failure in numerical computations of the exterior surface Helmholtz integral equation at certain characteristic frequencies is investigated. The problem of characteristic frequencies is numerically reflected in an ill-conditioning of the coefficient matrix arising from t
