Abstract

EMI shields and Salisbury type structures have been constructed from polyaniline. Shield characteristics have been measured in the frequency range of 100 kHz–110 GHz. In case of EMI measurements the shielding efficiency increases as a function of frequency above 1 GHz. The Salisbury structure utilizes a 377 Ohm/sq polyaniline layer and shows a high absorption at 59 GHz. The screen has a 3 mm air gap between the metal surface and the polymer layer.
