Full SPICE model for transfer impedance and transfer admittance inclusion in shielded coaxial cables analysis

A SPICE circuit model for the evaluation, in both the frequency and time domains of the coupling of a shielded coaxial cable with an external electromagnetic source is developed. The proposed equivalent circuit takes into account the presence of both the transfer impedance, and the transfer admittance and does not need this subdivided into elementary cells. All needed computations are executed, in the form of equivalent active and passive networks, inside the SPICE environment without needing to resort to external CAD tools. The intermediate and final results are validated by means of a comparison with results evaluated by independent methods.
