In this letter, we present a robust conformal finite-difference time-domain (FDTD) algorithm for the accurate modeling of perfectly conducting objects with curved surfaces and edges. We illustrate the application of the algorithm proposed in this communication with two examples that include: 1) a quarter-wave monopole mounted on a perfectly conducting elliptic disk, and 2) a cylindrical cavity. We show that the agreement between the conformal FDTD and other available methods is good. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 27: 136–138, 2000.
