Validation of MOM/FEM in modelling studies of loaded enclosures with apertures

In this paper to obtain of electromagnetic field distribution inside loaded enclosure with aperture, we present hybrid formulation which combines method of moments (MoM) and vector finite element method (FEM). While FEM is used for solving electromagnetic fields inside of the enclosure, MoM is used for solving the surface integrals related with the aperture field components using equivalent surface currents. To obtain efficiency of the proposed method, first applied to empty enclosure and the results are validated by comparing with literature. Then the method applied to loaded enclosure Shielding effectiveness, stored electrical energy and dissipated power in load are examined.
