【 摘 要 】

Analytical model has been developed for the shielding effectiveness of a rectangular enclosure with wire mesh covering. The aperture covered by wire mesh is replaced by an equivalent impedance which contains the surface resistance of the wire mesh. Based on the transmission line theory, the enclosure is modelled as a length of rectangular waveguide ended with a short circuit, then the shielding effectiveness (SE) of the enclosure can be calculated. By comparing the calculation with the full-wave simulation software, the proposed method is validated.
