The staircase-approximation time-domain (SATD) method is applied to transient analysis of nonuniform transmission lines (NTL) by employing cascaded uniform transmission line (UTL) sections and ABCD matrices. Numerical results to exponential nununiform transmission lines (ENTL) are verified with analytical formulae, both in time-harmonic and SATD forms, and the CAD tool PSPICE. This method also works well even for a lossy ENTL under the excitation of trapezoidal pulse chains.
