MLTRANS: A Time Domain Solution of the Response of Transmission Lines in a Photon Environment

This paper presents a time domain solution of the specialized transmission line equations found appropriate to characterize multiconductor photon-induced response. The treatment allows generalized N+1 conductor transmission lines with layered dielectrics. The series equivalent circuit takes the conventional form, but the shunt equivalent circuit is modified as described in the PEMTL development. The numerical techniques used in the coding of the problem follow those indicated by Merewether, which employ a "centered" finite difference methodology. This technique rapidly and accurately solves the time domain partial differential equations. Combined with a photon source code such as PEMTL, this solution provides a powerful research tool in the analysis of the photon induced response of complex multiconductor cables.
