Popis: This paper analyzes HIRF- and DCI-excitations of canonical structures regarding their surface current distributions. The latter are numerically computed for various test scenarios and investigated by Characteristic Mode Analysis. Based on the resulting modal decompositions, HIRF induced surface currents are expanded in terms of DCI modes with the intention to approximate radiated susceptibility tests by conducted ones. In order to allow existing deviations to be quantified, several metrics judging the equivalence of HIRF- and DCI-excitations are evaluated.
