摘要：

The goal of the present paper is connected with spectral quasi-optical ellipsometer (SQOTE) creation, based on the hollow dielectric beamguide and beamguide components as a quasi-optical transmission line. Ultra-broadband quasi-optical transmittance line provides operation of the ellipsometer within 0.17-0.225 THz (1.2-1.8 mm) frequency range. The set of elements of the transmittance line, which require matching with the generator, was determined. The principle and details of SQOTE measurements were described and its accuracy was estimated. Experimental testing of the ellipsometer was carried out by comparing dielectric constants of a set of materials measured by the setup with reference data and with the results of independent reflectometry measurements.
