Extraction the diagonal and off-diagonal components of permittivity tensor using terahertz time-domain polarimetry

Terahertz time-domain spectroscopy is a unique spectroscopic technique that determines amplitude and phase change resulting from terahertz wave interaction with material. The method terahertz time-domain polarimetry may be an alternative method. It is a characterization technique in which the change of polarization state of the wave transmission through the sample is measured. We propose analytical description of extraction the diagonal and off-diagonal components of permittivity tensor of materials in the terahertz frequency range using terahertz time-domain polarimetry. Using the diagonal and off-diagonal components of the permittivity tensor of materials, the effective mass, Hall mobility, and scattering time can be calculated.
