Additional information

<01 >In this paper a unique finite-difference time-domain (FDTD) method is described using an elliptical-cylindrical spatial-grid for time-domain Maxwell's equations to accurately and efficiently model conformal elliptical-cylindrical patch antennas, and overcome stair-casing errors that are encountered when a Cartesian spatial-grid is used for modeling curved surfaces. This method obviates coding complexity encountered in modeling of curved surfaces which is manifest using CP-FDTD or CFDTD techniques. Characterizing expressions representing the absorbing boundary condition and Courant stability condition are presented and used to provide a highly effective algorithm to model conformal antennas. Compared to commercial HFSS, the proposed FDTD algorithm is substantially faster by a factor of 28.
