“…In 1980, Taylor and Spadacini et al initially studied the field-to-line coupling model of twisted wire pair (TWP) placed in the reference plane [6][7][8] and free space [9]. In [10], the crosstalk between multi-core twisted wires with equal and unequal twist rate was compared, and [11] proposed a multiconductor TLM for analyzing crosstalk of shielded random twisted pair bundles. In addition to crosstalk, [12] studied the influence of non-uniform twist-pitch on the radiated susceptibility of a TWP, and [13] studied the random response of non-uniform multi-strand twisted pairs (MTB-TWP) excited by random plane waves.…”

In this paper, a multi-core twisted wire model with random non-uniform twists is established. The random combination of complete and non-complete pitch sections is used to accurately simulate the randomness of actual multi-core twisted wires. On the basis of the model, the cross section of the cascaded MTL is obtained, and a neural network algorithm is used to describe the complex relationship between the arbitrary position of the multi-core twisted wires and the unit length parameters. The unit length parameters at any position are obtained by cross section rotational transformation and random transposition transformation between conductors. Finally, the crosstalk in electromagnetic compatibility performance is calculated, and different termination impedances are analyzed. The results show that the crosstalk of multi-core twisted wires is susceptible to the effects of twisting and termination impedance at high frequencies, and the reliability of the proposed method is verified by comparison with full-wave simulation.

“…The research on TWP mainly focuses on its non-uniform characteristics and crosstalk solving methods. In [8], a new non-uniform TWP modeling method is proposed to simulate the change of the center position of the TWP. G. Spadacini et al proposed a prediction model of low-frequency nonuniform TWP crosstalk under plane wave excitation [1][2].…”

In this paper, a new algorithm for predicting per unit length (p.u.l) parasitic parameters of transmission line is proposed. In the twisted-wire pair (TWP), different rotation degrees correspond to different parasitic parameters, which brings difficulties to the solution of telegraph equation. At present, the mainstream method is to divide TWP and use the cascade theory to solve each segment as a parallel transmission line. Therefore, we propose to use the beetle swarm optimization (BSO) algorithm to optimize the weights of the back propagation neural network, use a certain sample to train the network. This algorithm is used to predict the p.u.l parameters of uniform and non-uniform TWP, and the finite-difference time-domain (FDTD) method is used to solve telegraph equation. Among them, the crosstalk value of the uniform TWP is compared with the simulation value in the CST to verify the effectiveness of the proposed algorithm; the non-uniform TWP performs 500 random generation calculations to give the maximum envelope value of the crosstalk.INDEX TERMS Beetle swarm optimization (BSO), crosstalk prediction, finite-difference time-domain (FDTD), multiconductor transmission lines (MTL).
