Characterization of EMC Shielding Materials

Electromagnetic shielding options have been greatly advanced by the introduction of new nanomaterials. Traditional methods of evaluating the shielding effectiveness of these materials do no adequately convey the relative effectiveness of these materials in actual applications. This project investigates the methods used to quantify the effectiveness of nanofiber composite shielding materials and proposes new methods that are better able to describe the effectiveness of these materials when used to construct shielded enclosures.
