Abstract-This paper presents a multiconductor reduction method for modeling electromagnetic crosstalk of complex cable bundles in the vicinity of a 60 degree corner. Based on the image theory and wide separation assumption, the per-unit-length parameters of the cable bundle can be obtained analytically. A modified six-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundle model compared with the original equivalent cable bundle method (ECBM). Numerical simulations are performed to demonstrate the viability and effectiveness of the method. This work can find wide applications in real environments.

“…Moreover, it was modified in [5] for modeling EM field coupling to the twisted-pair cables based on the assumption that the differential signal lines play a leading role in the equivalence procedure. 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].…”

“…Up to now, the establishment of the reduced cable bundle cross-section geometry only can be implemented either above an infinite PEC ground plane [2][3][4][5], inside a cylindrical cavity [6] or in the vicinity of a 60 degree corner [8] through the analytical formulas. However, no analytical formulas are available for direct reconstruction of the reduced cable bundle cross-section geometry model within arbitrary complex structures as Fig.…”

Abstract-In this paper, the equivalent cable bundle method (ECBM), an efficient simplified modeling method of the complex cable bundles, is modified for crosstalk prediction of complex cable bundles within uniform structure with arbitrary cross section. The foremost attributes of the modified method are a) the cable bundle within uniform structure with arbitrary cross section can be mapped to equivalent cable bundle above an infinite perfect electric conductor ground plane during the equivalence procedure, b) the culprit and victim conductors are divided into two groups separately during the grouping process, denoted as the culprit group and victim one, which do not participate in the equivalence procedure compared with the original ECBM for crosstalk problem, c) an effective eightphase procedure is established to define the electrical and geometrical characteristics of the reduced cable bundle model. Numerical simulations performed on a selected cable bundle surrounded by a rectangular cavity illustrate the efficiency and the advantages of the method. This method is considered as a key step for the ECBM to find wide applications in real systems.

A novel multi‐conductor electromagnetic coupling model for the sensitive‐wire subject to driven wire in a high‐precision machining workbench is proposed in this paper. The general coupling model for an N‐wire system is derived and is used to evaluate the wire coupling effect. Furthermore, 4‐wire and 3‐wire models are demonstrated to verify the accuracy through full‐wave electromagnetic simulation below 10 MHz. The results show that the error between the proposed method and the full‐wave electromagnetic simulation is less than 10%, demonstrating the high efficiency and accuracy of the proposed method. When the parameters of the driven power wire and the most sensitive wire are fixed and the parameters of neighboring wires are swept, the maximum fluctuation of the induced current on the most sensitive wire is 6.1 dB. The efficient calculation method proposed in this work helps reduce the risk of electromagnetic interference in complex electronic systems and improves the design efficiency of wires. It is promising to become a high‐performance method with high efficiency and precision.
