In this paper, we will present a low losses multiconductor transmission lines model valid both in the time and the frequency domains. This model is an extension of the characteristics method (Branin method) valid for lossless lines. Our model permits to describe the line as a quadripole whose advantage is to avoid the presupposed applied charges conditions in its extremes. This permits it to be...

A time-domain technique for the solution of arbitrary nonuniform multiconductor transmission lines (NMTL’s) is presented. The technique is based on a weak formulation of the NMTL equations obtained through spatial expansion of the voltage and current vectors into biorthogonal wavelet functions. Wavelets allow adaptive representations of the solution by using few expansion coefficients, with any...

The paper deals with a technique of sensitivity calculation in linear hybrid networks containing elements with both lumped and distributed parameters when the multiconductor transmission lines (MTL) are considered as the distributed parts. The technique utilizes the modified nodal analysis (MNA) method to do overall description of the network enabling determining sensitivities with respect to b...

Systems are considered consisting of an arbitrary number of multiconductor transmission lines joined and terminated by arbitrary linear networks. The fines are assumed to be Iossy, with frequency-dependent parameters. The system is analyzed in the frequency domain, and the inverse Fourier transform is used to obtain tbe time-domain response.

This thesis examines the effects of electromagnetic interference (EMI) and coupling in circuits and systems. The coupling phenomenon is investigated in nonuniform transmission lines and adjacent via structures in microelectronic circuits. Radiation from metallic enclosures with apertures and lined with resistive materials is analyzed. Electromagnetic interference on a larger scale is studied in...

In this paper, we present a generalization of the simultaneous diagonalization technique by means of congruence transformations to the general reciprocal lossy multiconductor transmission line case. The method paves the way to solving the inverse problem, i.e., given a lossy multiconductor transmission line system of a given length, recover the transmission line parameters from the impedance or...
