The antireflective properties of DMSO-doped poly (3,4-ethylenedioxythiophene):poly (4-styrenesulfonate) (PEDOT:PSS) thin films produced by spin coating at THz frequencies is reported. The reflected pulses from the silicon substrate are observed to change with the doping concentrate and the thickness of the DMSO-doped-PEDOT:PSS films. Theoretical analysis based on an equivalent transmission line circuit model has been used to understand the experimental results. Excellent antireflective properties is achieved by 10 vol% DMOS-doped-PEDOT:PSS films. The normalized main pulse transmittance remains as high as 70%, and the minimum reflected pulse transmittance is only 3% at 0.52 THz. This work paves the way for PEDOT:PSS-based THz antireflection coating.
