Spatial Filter Housing for Enhancement of the Shielding Effectiveness of Perforated Enclosures with Lossy Internal Coating: Broadband Characterization
Figure 19
Shielding effectiveness versus frequency for an internally coated 30 × 12 × 30 cm3 enclosure with a 10 × 10 cm2 aperture illuminated by a plane wave at normal incidence with a spatial filter of 3 × 5 conducting strips, placed 4 cm away from the aperture.
