The electromagnetic interference (EMI) performances of the interconnects and cables can be predicted via a standard multi-conductor transmission line (MTL) model, while latter is not valid for evaluation power rail collapse ground bounce responses. To circumvent limitations, more general feasible improved MTL representation presented in this paper. It physically incorporates partial resistance ...

A wavelet approach to the analysis of nonuniform high-speed interconnects with frequency dependent parameters is presented in this paper. The nonuniform interconnects are modeled by the use of nonuniform multiconductor transmission line equations in the frequency domain. Two different methods are proposed here (differential and integral formulation): in both of them the space variable is expand...

As the circuit density of pattern traces and the data rate on a printed circuit board (PCB) is increased, an unexpected electromagnetic interference (EMI) such as crosstalk can degrade the intended signal transmission. The crosstalk problems on multiconductor transmission lines (MTLs) which are parallel and have the same length have been researched by C. R. Paul[1]. In case of shifted parallel-...

This paper investigates a measurement method that characterizes lossy printed multiconductor transmission lines, its accuracy, the choice of measurement representations, and some simple approximations. We illustrate the method with measurements of a pair of lossy coupled asymmetric microstrip lines.

-This paper presents an attempt to formulate a high-level description of the optimal transmission line simulation method. To formulate the optimal approach, most significant aspects of the problem are identified, and alternative approaches in each of the aspects are analyzed and compared to find the combination that results in the maximum efficiency, accuracy and applicability for the transient...

Boards F. Sabath , H. Garbe University of Paderborn C-LAB, Paderborn, Germany University of Hannover, Hannover, Germany Abstract This paper deals with the coupling between traces on Printed Circuit Boards (PCB). Particularly a method is presented which allows to estimate the deviation of the current distribution on an active trace due to the omission of recoupling by an adjacent trace. An e ect...

This paper examines modal cross power in electromagnetic transmission lines. It shows that the cross powers of nearly degenerate modes may be large in quasi-TEM multiconductor transmission lines typical of modern electronic circuits at moderate and low microwave frequencies. The paper develops simple expressions to estimate the magnitude of these cross powers from the “power-normalized” conduct...

In this work, we used the finite element method (FEM) and the multiconductor transmission lines (MTL) method for designing an UHF magnetic resonance imaging (MRI) probe. This radio frequency (RF) volume coil quasi-transverse electromagnetic (quasi-TEM) type, based on the use of 16 microstrip transmission line elements has been developed for in vivo hydrogen magnetic resonance (HMR) application ...

The lightning performance of an overhead Multiconductor Transmission Line (MTL) system is typically represented by means of curves reporting how many lightning faults per year the system may experience as a function of its insulation level [1]. In other words, it expresses the probability that the lines are subject to an overvoltage greater than their critical flashover voltage (CFO). Such curv...
