Measurement and Simulation of the Induced Current on a Wire Using S-Parameter Method

This study investigates the measurement of current on a wire located inside a cavity with an aperture as a function of excitation frequency with the use of a simple S parameter model. Validation is provided by comparing simulations and measurements. Using this approach, it will be possible to make an accurate prediction of the current distribution on the wire, and thereby to describe potential interference effects to equipment placed along the wire bundle at frequencies of interest.
