Abstract
Estimates of the linear optical properties of promising material for the THz modulators manufacture, i. e., thin films of the mixture of tungsten disulfide and boron nitride with hexagonal lattice on polyethylene terephthalate (PET) substrate in the broadband terahertz frequency range are presented in this paper. In the range from 0.5 to 2.5 THz the films showed high transparency exceeding 90%. The calculated refractive index value 1.75 exceeded the ones for TPX and PET – materials used in the manufacture of THz optics.

..........The studies were carried out using a laboratory setup
of THz time-domain spectroscopy of TeraPulse 4000
manufactured by TeraView, shown in Fig. 1. In this
system, a photoconductive antenna illuminated by
the radiation of a femtosecond (fs) fiber laser is used......
