A simple theory for predicting the electromagnetic performance of enclosures using impedance and polarizability measurements
Abstract
The theory of Madle and Hoeft (1982) for understanding the magnetic field attenuation of enclosures has been refined so that it can be used to quantitatively predict the electromagnetic performance of electrically small enclosures. Using the transfer impedance of the joints, the surface impedance of shielded apertures, and the polarizability of apertures, this theory predicts the surface magnetic field attenuation (the ratio of the surface magnetic field on the exterior of the enclosure to the magnetic field inside the enclosure).
