The Time-Domain Contour Integral Method—An Approach to the Analysis of Double-Plane Circuits

The time-domain counterpart of the Okoshi's contour integral method is formulated with the aid of the reciprocity theorem of the time-convolution type. A numerical procedure for solving the time-domain reciprocity relation is proposed and validated using an analytical solution based on the eigenfunction expansion and the finite-integration technique. For the former, the time-domain counterpart of the classical double-summation formula for a rectangular power-ground structure is found and evaluated.
