This report discusses a number of modifications of a single-wire transmission line model for use in EMP internal interaction studies. The importance of including the effects of local line perturbations (such as a cable clamp) is discussed in terms of the reflection coefficient presented to waves on the transmission line, and general curves for determining when to neglect such effects are given. Next, the behavior of a finite-length transmission line with periodic loading is investigated and results are compared with those of an infinite line using Floquet's theorem. Finally, the bulk current response of a general multi-conductor transmission is related to the current on a single-wire line and a prescription for determining an equivalent single-wire characteristic impedance and a load impedance from the multiconductor quantities is described.
