Electric and magnetic coupling parameters are measured for a braided- shield cable. Starting with a general solution for the internal response of an externally excited cable, simple expressions which relate the coupling parameters to the internal and external currents and voltages result when the electrically short line approximation is used. These expressions are applied to experimental configurations in which the external excitation is either predominately magnetic or electric, and the internal loading is configured to exclude either the electrically or magnetically induced internal currents. The experimental results are compared with theoretical calculations appearing in the literature, and the relative importance of the electric and magnetic coupling effects is discussed.
