Abstract
The exact image theory is here applied to study the transient shielding effectiveness of a canonical shielding configuration, i.e., a small current loop in the presence of a parallel planar thin conductive sheet. In particular, the Green function providing the electromagnetic field produced by a pulsed vertical magnetic dipole in the whole space is derived in a closed analytical form. The recently introduced definitions of transient shielding effectiveness are used to evaluate the shielding properties of the configuration. The derived results allow for calculations in a closed form for simple transient waveforms of the exciting currents.File | Dimensione | Formato | |
