Microstrip lines not parallel to the FDTD grid are analyzed accurately using singularity‐enhanced FDTD equations. It is assumed that the metal strip is infinitely thin, and its edges are diagonal to the FDTD cell faces. It is found that the enhanced‐equations technique models wave propagation accurately, even when the grid is very coarse. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 121–123, 1999.
