3D-FEM analysis for shielding effects of a metallic enclosure with apertures

Abstract

The leakage of electromagnetic (EM) waves from a metallic enclosure with apertures, from a metallic mesh and from a metallic shield thinner than the skin depth are numerically analyzed using a three dimensional finite element method (3D-FEM). The calculated results were compared with measured results using a simple shape model enclosure with a generator inside. The phenomena predicted by the numerical analysis agree with the measurement results.
