“…Operators , , , , and are defined by expressions (2) and (3). The combined complex amplitude is (7) where i is the ordinal number of the satellite wave propagating through the sample and k is the number of satellite waves taken into consideration in calculations. The number of summed up waves is physically unlimited, and, in general, the expression (l, ν t ) (ν t )) i can be represented as a sum of geometric progression: (l, ν t ) (ν t )/(1 + (l, ν t ) (ν t )).…”

“…Water molecules exhibit a large dipole moment and an extremely rich spectrum of rotational and vibrational degrees of freedom. Therefore, the THz spectral characteristics of water reveal numerous peculiarities and substantially vary upon changes in conditions of the surrounding medium [5][6][7]. Major part of the relict cosmic radiation, which has the spectral composition typical of a blackbody radiation with a temperature of 3 K, falls into the microwave and THz regions of the electromagnetic spectrum [8,9].…”

We have developed an algorithm for solving an inverse problem related to the reconstruction of spectral dependences of terahertz (THz) optical characteristics of a homogeneous medium in the form of a plane-parallel plate, which is based on processing signals obtained by a THz time-domain spectrometer. In contrast to existing methods, the developed algorithm allows studying the optical properties of dielectric samples that have a small thickness (down to 0.1 mm) and low index of refraction. Optical characteristics in the THz spectral range are determined by minimization of the error functional constructed based on experimental and theoretical complex transfer functions of the sample, wherein the theoretical transfer function is obtained by using a model of a Fabry-Perot quasi-resonator. The proposed method is experimentally verified by studying optical properties of test samples. The reconstructed THz optical characteristics are compared with the characteristics of the same test media obtained by means of the THz backward-wave oscillator spectroscopy, which allowed estimating the accuracy of the proposed method.
