Comparing analytical and numerical calculations of shielding effectiveness of planar metallic meshes with measurements in cascaded reverberation chambers

• Large electrical systems or facilities can be satisfactorily shielded by using low-cost meshed metallic nets. Here the shielding effectiveness for two such planar meshes is calculated analytically and verified both experimentally by using cascaded reverberation chambers as well as numerically with results computed using a full wave electromagnetic solver. It is shown that all three methods agree and, in addition, that non-square shaped aperture meshes can be handled with an equivalent square area shaped aperture.
