The Moisture Measurements of Industrial Materials and Articles by using Millimeter Waves

The development of methods for controlling the quality of industrial materials and articles refers to the most important directions of scientific and technical progress. At present the radiowave non-disturbance control based on the interaction of an electromagnetic wave with the object controlled is promising. The UHF-method of the control is widely spread today. One of the fields of using UHF-methods is the control of moisture of materials and articles. In the present report the results of experimental measurements in the short wave part of the millimeter (mm) wavelength range of the transmission coefficient of the quasi-optic cuvette filled with materials under investigations (cement, sugar) are presented.
