Abstract
To study the S-parameters and dielectric permittivity of polycor and GaAs samples, a vector network analyzer R4-MWM-118 with a special measuring cell and a modified Nicholson–Ross–Weir method were used. The use of polynomial Chebyshev criteria in R4-MWM-118 for approximation in digital filtering made it possible to reduce the distortion of the achieved approximations of S-parameters. The use of digital filtering made it possible to eliminate the subjective error of the operator in the analysis and measurements with the presence of a “noise” component, to improve qualitatively the perception of the amplitude-frequency characteristic and to exclude uninformative changes in the instrument readings at any point in the frequency range. The dependences of the amplitudes and phases of the transmission and reflection coefficients, as well as the dielectric permittivity of the samples under study on the frequency in the range 78.33–118.10 GHz are obtained.
