Simplification Method for Modeling Crosstalk of Multicoaxial Cable Bundles

Abstract

Abstract-In this work, a new efficient simplification method is proposed for crosstalk prediction of multicoaxial cable bundles (MCCB). The purpose of the new simplification method is to reduce the simulation time by reducing the complexity of the complete cable bundle model. A modified five-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundle by making the outer and inner conductor of the coaxial cable participate in the equivalence procedure respectively. After a short presentation of the MCCB coupling problem, the theory fundamentals of the new simplification method and numerical simulations performed on a simple MCCB are presented to demonstrate the efficiency and the advantages of the new simplification method.

Application of the "Equivalent Cable Bundle Method" for Modeling Crosstalk of Complex Cable Bundles Within Uniform Structure With Arbitrary Cross-Section

“…In this section, compared with previous papers [1][2][3][4][5][6][7][8][9], the differences and also the challenging points of the proposed method are the grouping of conductors and the building of the cross-section geometry of the reduced cable bundle model, which are detailed in the following paragraph. As far as the EM crosstalk is concerned, the approximate assumptions including a) all conductors are PEC and the surrounded medium is lossless, b) only transverse electromagnetic (TEM) mode is considered.…”

“…In [6], it was adopted to predict the crosstalk of a cable bundle within a cylindrical cavity which is considered as the ground return. Then it was further studied and applied for predicting electromagnetic compatibility issues of complex cable bundle terminated in arbitrary loads [7] or in the vicinity of a 60 degree corner [8] and also adapted to model the crosstalk of multicoaxial cable bundles [9].…”

Crosstalk analysis of uniform and nonuniform lossy microstrip‐coupled transmission lines

“…In Reference , a simple technique is introduced for crosstalk estimation of MTL at low frequencies. This technique is applied only for a shielded uniform multi coaxial cable bundles and can be applied in those cases, in which the terminated impedances are enough larger or smaller than the victim and culprit characteristic impedance.…”

Network Expression for Coupling Analysis of Arbitrarily Directed Multiple Transmission Lines

“…Crosstalk analysis has been studied for parallel MTLs using network functions based on the telegrapher's equations under the assumption of transverse electromagnetic (TEM) mode propagation or at least quasi-TEM mode propagation [1,2]. Recently, a new efficient simplification method is proposed for crosstalk prediction of multicoaxial cable bundles [3].…”
