Transient analysis of nonuniform transmission lines

The transient propagation through nonuniform transmission line structures is analyzed. Nonuniform structures include tapered microstrips and uniform lines with periodic and nonperiodic loadings or discontinuities. The analysis employs a scattering parameter formulation in the time domain to derive closed-form algorithms for the voltage and current variables in the line. The solutions that can be used in the case in which both discontinuities and terminations are nonlinear avoid the use of transforms or convolutions and thus are computationally efficient. Simulation algorithms are tested and, when compared with experimental simulations, indicate good agreement
