Abstract

The incorporation of dispersive behavior of power-ground structures in the time-domain contour integral method is investigated. It is shown that material dispersion can be accounted for with the help of a numerical method for the inverse Laplace transform. The proposed technique is very versatile and allows for the incorporation of the general (causal) dielectric-relaxation model. In this paper, conduction-loss and Debije´s dielectric-relaxation models are closely studied. Numerical examples are validated using the feature selective validation analysis.
