In this paper the coupling of fields into the interior of a cylindrical metallic cavity with apertures is investigated, both numerically and experimentally. The question arises whether and to what extent the internal field distribution can be determined in a method of moments (MoM) based simulation. It is known from literature that the classical electric field integral equation (EFIE) approach is not able to provide a zero field inside a completely closed body. Hence the in-coupled fields may become distorted by the superposition of spurious solutions also in the presence of small apertures. It will be demonstrated that an integral equation approach which is based on two different electric current layers provides solutions which are in a good agreement with measured results. The obtained results are interpreted with respect to EMC requirements in aircraft. © 2011 EMC Europe.
