The recently proposed transient shielding effectiveness (SE) is investigated for a near-field Huygens source. It is shown, that similar normalization factors as introduced in case of electrical and magnetic dipoles are valid and can easily being combined for the present case. The analysis ends up with a transient SE which is more realistic as compared to several types of actual near-field sources. Moreover the results for that case are better compatible with plane-wave (far-field) illuminations. For a time-harmonic incident field the transient SE (that is, the electromagnetic SE) turns out to be identical for both, incident plane-wave and near-field Huygens source. Numerical results confirm the theoretical derivations.
