“…Because of proximity between PCB interconnect lines and cables, undesirable effects as electromagnetic interference (EMI) and crosstalk coupling [1][2][3][4] are unavoidable and susceptible to degrade the electronic circuit performances. The crosstalk modelling becomes one of research topics attracting massively the electronic design, test and EMC research engineer attention [4][5][6][7][8][9][10][11][12][13]. Predictive approaches for analyzing PCB TL coupling need to be developed.…”

A theoretical investigation of distributed microwave circuit built with Ti-shape topology is developed. The topology under study consists of neighbored T-and i-shape interconnect lines. The Titopology equivalent S-matrix is calculated as a function of crosstalk coupling coefficient and coupled line (CL) delay. To highlight the NGD modelling feasibility, parametric analyses with respect to the T-and ielement coupling and delay are introduced. More practical validation is carried out with designed, simulated and measured microstrip prototype. It is found that because of T-and i-crosstalk, the Ti topology can behave as a bandpass NGD function. A good NGD performance with NGD level of approximately-1 ns around the center frequencies 2.2 GHz with transmission coefficient of approximately-2.1 dB and reflection coefficient better than-14 dB. The measured results are in good agreement with calculated models and simulations. Two-cell Ti-NGD circuits were also investigated to illustrate the designability of the topology for multi-band and widened single band NGD responses.

“…More restrictive conditions may apply for highly nonuniform fields in the near-field region of field sources, or in resonating environments [17]. Anyway, it is worth remarking that these requirements for the segmentation are not so severe as those correlated with wire twisting and involved in some models cited in Section I [7], [8].…”

“…Specifically, for the prediction of crosstalk in bundles composed of TWPs, this approach was used in [7], where the MTL was subdivided into half-twist sections, and in [8], where a finer segmentation into 6−50 sections per twist was proposed. Given the short length of the twist pitch in common applications (less than a few centimeters), the use of a dense segmentation would significantly increase the computational burden required for modeling long cable harnesses.…”

An approximate multiconductor transmission-line (MTL) model is developed for predicting the radiated susceptibility of bundles composed of twisted-wire pairs (TWPs) running above a ground plane, and illuminated by a nonuniform electromagnetic field. Through the use of averaged per-unit-length parameters and sampling of the incident electromagnetic field, the nonuniform MTL is modeled as an equivalent uniform MTL including common-mode (CM) voltage sources accounting for fieldto-wire coupling effects. The proposed model is able to predict CM currents/voltages induced in the terminal loads of every TWP in the bundle. In particular, it is shown that the CM noise significantly differs depending on the position of the considered TWP in the bundle cross section. Comparison of results versus full-wave simulations validates accuracy and computational efficiency of the proposed model.Index Terms-Common mode (CM) and differential mode (DM), field-to-wire coupling, multiconductor transmission-line (MTL) model, twisted-wire pair (TWP).

“…One of the most common examples are twisted wire pairs (TWPs), which are used to transfer information in communication systems due to their high immunity to both conducted [6] and radiated [7] electromagnetic interference. Many other contributions addressed the EMC modeling of the TWP performance in terms of susceptibility to external fields [8]- [11] or wave propagation and crosstalk [12]- [16]. A second example of a NUTL is a hand-assembled cable bundle, where the (random) meandering of wires yields a geometry far from being uniform along the line [17]- [19].…”
