Time Domain Computation of Full-Wave Partial Inductances Based on the Numerical Inversion of Laplace Transform Method

This paper presents the computation of time-domain partial inductances. The numerical inversion of the Laplace transform (NILT) is adopted to compute the time samples of the partial inductance. Furthermore, the causality can be strictly guaranteed by using a delayed implementation of the NILT method making use of the minimum distance between the spatial supports of the basis functions. The proposed method is tested by comparing the results with analytical ones existing for coplanar zero-thickness regions and with inverse Fourier transform techniques for non-orthogonal volumes.
