Abstract
EMI shields and Salisbury type structures have been constructed from polyan iline. Shield characteristics have been measured in the frequency range of 100 kHz - 110 GHz. In case of EMI measurements the shielding efficiency inc reases as a function of frequency above 1 GHz. The Salisbury structure util izes 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 lay er.
