A non-orthogonal time-domain full-wave solver, is developed based on the discrete surface integral (DSI) technique. Closed form expressions are derived for the coefficients used in the leap-frog computation scheme so that the DSI technique can be implemented as a generalised finite-difference procedure. This procedure is employed to investigate the propagation characteristics of a typical interconnect via in printed circuits. The numerically calculated scattering parameters show consistent behavior with measured results. A square via with equal area is also evaluated.
