Analysis of Resonance Elimination in a Shielding Enclosure with Aperture Using CBP Material

Yi Zhang | Kangbo Tan | Hongmin Lu

Abstract: The resonance elimination for the shielding enclosure is theoretically investigated. An absorbing nanomaterial, one- dimensional carbon nanotube @ barium titanate @ polyaniline composite (CBP), is used at different positions in the enclosure with an aperture to eliminate the resonance. Modified equivalent circuit model is applied to calculate the shielding effectiveness (SE) and analyze the elimination of the resonance. Results show that 20mm and 30mm thick CBP attached to the back of the aperture plate, end of the enclosure or both can improve the minimum of the SE and eliminate the resonance obviously. And the case of two pieces of 30mm thick material attached to the back of the aperture plate and the end of the enclosure meanwhile is the best.
