Braid Shielding Effectiveness Kron's Model via Coupled Cables Configuration

This brief develops a circuit theory on shielding effectiveness (SE) Kron's modelling of parallel coupled nude-braided cables. The model is established via the approach of tensorial analysis of networks (TAN). The cable structure graph is elaborated from the lumped equivalent circuit including the braided cable transfer impedance. The SE is formulated from the branch and mesh space analyses by the mean of Kron's formalism. To verify the relevance of the SE TAN model, comparisons with commercial tools using SPICE and 3D design full wave simulations are performed. As expected, the computed SE from 150-MHz to 750-MHz with tens-centimeter lengths cable braided assumed having 95.5% optical coverage is in good agreement with simulations.
