Efficient dispersion relations for terahertz spectroscopy

The authors introduce dispersion relations that provide an efficient tool in analysis of the experimental data in reflection terahertz spectroscopy when both the real and imaginary parts of the response function can be measured. These dispersion relations allow one to check the consistency of the measured spectra of the real and imaginary parts of the complex reflection coefficient, and moreover to remove the sample misplacement error from the measured spectra.
