Abstract :
Terahertz (THz) neutral density (ND) filters are a useful components in THz system, and have recently attracted s much interest. In this paper we report on the potential of PEDOT/PSS conductive polymer thin film doped with a polar organic compound dimethylformamide (DMF) as a THz ND filter. The THz transmission through the thin film is controlled by the DMF doping concentration.
