Shielding effectiveness evaluation and optimization of resonance damping in metallic enclosures

The evaluation of the shielding effectiveness of metallic enclosures with apertures containing metallic objects and excited by arbitrary sources is the main topic of this work. The shielding effectiveness is computed through an integral formulation based on the Method of Moments which makes use of a fast computation of the enclosure Green functions. Absorbing artificial materials are also designed and proposed to damp the resonant fields excited inside the enclosure in order to improve the shielding performance.
