Enhancement in Shielding Effectiveness by Electromagnetic Absorbers Applied to Aperture of Metallic Enclosure
This study introduced a method for enhancing the shielding effectiveness of an enclosure with apertures using an absorber. The absorber was installed on the inner surface of the aperture of the enclosure and attenuated incident electromagnetic waves as they passed through it. Furthermore, the absorber reduced the standing waves generated inside the enclosure owing to the cavity effect, improving shielding effectiveness. A 3D numerical analysis confirmed that the proposed structure enhanced the shielding effectiveness of the enclosure.
