Generalized Time-Domain Adjoint Sensitivity Analysis of Distributed MTL Networks

In this paper, a generalized approach is presented for time-domain adjoint sensitivity analysis of lossy multiconductor transmission lines (MTLs) with respect to electrical and/or physical parameters. While the new approach provides all the advantages of an adjoint sensitivity analysis, it is independent of the specifics of the MTL macromodel used. Several numerical examples are presented to demonstrate the validity and accuracy of the proposed approach.
