Abstract
In this work an approximated method to obtain
Shielding Effectiveness of metallic enclosures with an
aperture is evaluated. The method consists of the analysis
of the 2-D transversal cut of the structure through a
numerical method. A Finite Element Method based CAD
tool, has been used in order to obtain the results for the
susceptibility analysis of the structure. To obtain the level
of energy coupling between the inner and outer part of
the cavity an empirical formula is used. Shielding
Effectiveness of metallic enclosures with different sizes
and apertures has been analysed and good agreement has
been found between the 2-D approximated method and
measurements. This tool can be used to study shielding
properties of materials and the effects of enclosure
contents, PCBs, I/O devices, etc.
