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.
