Summary:The confidence in shielding effectiveness (SE) measurements on enclosures according to IEC TS 61587-3 is evaluated. A methodical analysis using an electromagnetic topology (EMT) based model is carried out to find the electromagnetic (EM) critical aspects. The EMT model represents the interaction between base and auxiliary components which are necessary for testing. As shown in examples, each local coupling effect can be investigated by means of an appropriate, numerical or experimental method. It is displayed how the EMT facilitates the translation of local estimations into the global SE test result.
