Waveform relaxation analysis of nonuniform lossy transmission lines characterized with frequency-dependent parameters
TLDR
In this article, an efficient method for the transient simulation of nonuniform frequency-dependent transmission lines is presented, which consists of iterative waveform relaxation analyses of asymmetric disjoint two-port networks constructed with FFT waveform generators and characteristic impedances synthesized by applying the Gauss-Marquardt optimization technique.Abstract:
An efficient method for the transient simulation of nonuniform frequency-dependent transmission lines is presented. The method consists of iterative waveform relaxation analyses of asymmetric disjoint two-port networks constructed with FFT waveform generators and characteristic impedances synthesized by applying the Gauss-Marquardt optimization technique. The method can also be adapted for discrete-time analysis by replacing the FFT waveform generators with ideal transmission lines connected with waveshaping networks. Transient responses of uniform and nonuniform transmission lines with and without skin-effect parameters and terminated with linear and nonlinear loads are simulated for illustrations. The accuracy and efficiency of the relaxation technique are substantiated with exact analytical solutions and experimental data. >read more

Spectral-Domain Approach for Calculating the Dispersion Characteristics of Microstrip Lines (Short Papers)
Tatsuo Itoh,Raj Mittra +1 more
TL;DR: In this article, the boundary value problem associated with the open microstrip line structure is formulated in terms of a rigorous, hybird-mode representation, and the resulting equations are subsequently transformed, via the application of Galerkin's method in the spectral domain, to yield a characteristic equation for the dispersion properties of the OML line.
