Abstract :
A differential method for accurate extraction of the complete S-parameters from FD-TD simulations is proposed. In reciprocal circuits no a priori knowledge of reference impedances or field distribution in the ports is needed. The method is directly applicable to arbitrarily shaped and inhomogeneous transmission lines, oblique to the FD-TD grid.
