6. Shielded cables and enclosures

In the previous example, we considered the case of transmission via a cable shield. Overall, the transfer impedance has three expressions as a function of the braiding angle . These expressions are the coupling functions to be inserted in the coupling matrix [M]. The expressions for each type of braiding are :

{\begin{array}{l} ψ \approx 45^{\circ} \to Z_{t} = Z_{td} + j L_{t} ω \end{array}
