“…Unfortunately, in modern applications, the number of discrete sections of the line must be quite large to accurately account for all nonuniformities and increasing the number of sections reduces the efficiency of the method. Another technique, based on the method of characteristics [15], allows to convert the hyperbolic partial differential equations of the NUTLs into a set of ordinary differential equations. However, to account for frequencydependent p.u.l.…”

Abstract-A novel two-step perturbation technique to analyze nonuniform single and differential transmission lines in the frequency domain is presented. Here, nonuniformities are considered as perturbations with respect to a nominal uniform line, allowing an interconnect designer to easily see what the effect of (unwanted) perturbations might be. Based on the Telegrapher's equations, the proposed approach yields second-order ordinary distributed differential equations with source terms. Solving these equations in conjunction with the pertinent boundary conditions leads to the sought-for currents and voltages along the lines. The accuracy and efficiency of the perturbation technique is demonstrated for a linearly tapered microstrip line and for a pair of coupled lines with random nonuniformities. Moreover, the necessity of adopting a two-step perturbation in order to get a good accuracy is also illustrated.

“…Chang [ 191, assuming the knowledge of transmission line chain matrix, generalized the method of characteristics for frequency-dependent nonuniform lines. Orhanovic et al [20] have made contributions in the area of time simulation of the coupled lossy nonuniform transmission lines-solving numerically a system of characteristic equations for such a case. In this article, we utilized this approach accenting both the physical interpretation and computational efficiency.…”
