Abstract

Apertures in a rectangular enclosure can be the coupling path of electromagnetic interference (EMI). A multiresolution method of moments (MoM) formulation is used to evaluate the shielding effectiveness of metallic rectangular enclosures with aperture. To this end, electric field integral equation (EFIE) is formulated for the surface currents. The use of fine meshing near the apertures and edges enables accurate results. Using multiresolution analysis considerable saving in calculation time is obtained. A study of the influence of the apertures orientation is presented. Also the effect of considering different angles of incidence and polarization is shown to be significant.
