Abstract

In this paper, the use of plastic compound patches for removing radiated interferences inside electronic equipments is studied. Absorption and reflection properties of conductive polymers have been analysed in order to damp the resonances in a metallic enclosure. A 2D technique to obtain the shielding effectiveness of metallic enclosures with inner materials is evaluated. The influence of the conductivity of compounds and the location of the samples in the enclosure is studied. Results show that the 2D technique can be used to evaluate cavity contents or for design purposes.
