Spatial Filter Housing for Enhancement of the Shielding Effectiveness of Perforated Enclosures with Lossy Internal Coating: Broadband Characterization
Figure 15
Shielding effectiveness versus frequency of a 30 × 12 × 30 cm3 box-shaped enclosure with four 5 × 5 cm2 apertures arranged in two rows and two columns, illuminated by a plane wave at normal incidence in the presence and absence of a lossy internal coating of 1.5 cm thickness.
