Efficient post-processing procedure for combined FDTD/TL transient analyses

This paper proposes an efficient post-processing procedure to be used in the combined three-dimensional (3-D) finite-difference time-domain transmission line (FDTD/TL) analysis of low-frequency transient problems involving complex wire structures. The method allows automatic computation, from the 3-D-FDTD solution, of the transient source terms representing the inputs of the TL analysis.
