Abstract-An improved finite-difference time-domain (FDTD) method is proposed for predicting transient responses of coaxial cables which are placed in an electrically large metallic cabin with arbitrary slots and circular windows on its wall. By integrating nodal analysis, multi-conductor transmission line (MTL) equation and FDTD method, we are able to accurately capture electromagnetic interference (EMI) effects on the cables. Our developed algorithm is verified by calculating frequency-dependent transfer impedance of coaxial cables together with induced currents. Numerical calculations are further performed to show the near-end coupled current responses of braided and tubular cables, respectively, and the effects of incident directions and polarizations of the illuminated electromagnetic pulse are both taken into account.

an external electromagnetic pulses (EMP) wave can seriously disrupt or even destroy electronic equipments. The experimental study shows the electromagnetic coupling of EMP to imperfectly shielded cables is the main mechanism to induce transient interference. Then the mathematical model of field-to-line coupling effect is established. A solving approach which combines transmission-line equations with FDTD method is presented to calculate the induced voltage and current responses on the cable in time domain. Analysis of the coupling effect in different conditions is carried out. The study results can provide reference for the optimizing design of shielded cable against EMP.

“…There are several typical models to calculate the transfer impedance. Such as Tyni [2], Vance [3], S.Sali [4], Kley [5], Demoulin [6], etc. They have developed the formulas to calculate the three components in (1) on the basis of coupling mechanism on the braided shields.…”

A new model is presented for the accurate predictions of transfer impedance of braided coaxial cables, from a summary study on the earlier models proposed. The complicated responses on the braided shields due to the radiation from the exterior produced electromagnetic fields are taking into account in the new model. In addition, the diameter of braid is rebuilt to improve the accuracy of inductance. The formulas have a close relationship with the primary parameters of braided shield. The accuracy of the new model is studied against the calculation values for transfer impedance obtained from the earlier models proposed by Tyni, S.Sali, Kley and the measurement results of several braided cable samples.
