AB  - Composites were prepared by filling high density polyethylene (HDPE) with 
      acetylene black (AC-CB) and high-structure CB (HG-CB), respectively. Optical 
      properties of the composites were characterized with terahertz time-domain 
      spectroscopy (THz-TDS). It was found that as frequency increases the absorption 
      coefficients of the composites increase whereas the refractive indexes decrease. 
      Both the absorption coefficient and refractive index increase with increasing the 
      particle concentration. The HG-CB filled composites have larger absorption 
      coefficient but smaller refractive index compared with that of the AC-CB 
      composites at the same particle concentration. These phenomena are related to the 
      different particulate structures and aggregate structures of the CB particles. 
      Assuming that the dielectric loss in THz frequency range is mainly attributed to 
      the electron transport within the conductive clusters and the interfacial 
      polarization of HDPE, the information of relaxation time and relaxation strength 
      was obtained through fitting the experimental results to two-Debye theory of 
      dipole relaxation.
