An Introduction to Shield Joint Evaluation Using EMI Gasket Transfer Impedance Data

Abstract

The application of transfer impedance measurement techniques to characterize EMI shielding gasket mate­ rials produces data more useful to designers than do traditional shielded room techniques. Transfer imped­ ance, which is free of variations due to geometry and incident fields, allows more detailed evaluation of the roles played by shielding gaskets and their mating surfaces.
