Abstract

The study of nine different voltage pulses (exponential, rectangular, unit step, trapezoidal, logarithmic, triangular, quadratic, gaussian, and tangential), which approximate the unit impulse or dirac delta in finite difference time-domain (fdtd) simulation of grounded dielectric slab-like microstrips, was carried out in order to know how each one behaves when transient and steady state analyses are considered. All these pulses lead to almost identical responses (except the unit step) in the frequency regime but to very different performances in the time regime. The convenience of use one pulse instead of other is dicussed on the context of specific applications.
