Correlation between shielding effectiveness and transfer impedance of shielded cable

The correlation between the shielding effectiveness and transfer impedance of a 50 /spl Omega/ shielded cable was evaluated. The methods used in the performance of the investigation to induce the currents and voltages into the wires and cables were by use of an electric dipole antenna and a current probe. A direct correlation between shielding effectiveness and transfer impedance was recorded on a BNC cable that was terminated in 50 /spl Omega/ at both ends.
