Introduction of radiation losses in the time domain transmission line method

Because the transmission line method only allows to study the propagation of a pure tem mode along a line, all radiation phenomena are neglected. These phenomena become important when lines have discontinuities, then in this case radiating losses must be included in the theoretical formalism. This paper introduces an original approach to consider radiation of lines and to include them in a time domain transmission line method. Some comparisons with full modes method results validate the method.
