A nonorthogonal time‐domain full‐wave solver of Maxwell's equations was implemented based on the discrete surface integral (DSI) technique. Closed‐form expressions were derived for the coefficients used in the time‐advancing scheme, in order that the DSI technique could be applied as an explicit generalized finite‐difference‐time‐domain (FDTD) procedure. The FDTD‐DSI scheme was employed to investigate the wave‐propagation characteristics in multihole waveguide couplers. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 208–213, 1997.
