The method was developed specifically for the measurement of the newest nanoscale materials for use in electrically controlled microwave devices. The essence of the method reduces to the initiation of the main types of oscillations in the DR a thin dielectric substrate, the respective sizes of the waveguide or in a special measuring cell. The advantage of a thin cavity in a significant increase in sensitivity. Since the method of complex cavity, when the substrate with film is placed in the main DR, gives a frequency shift in megahertz unit, relative to the base without the film, the thin DR gives the displacement of hundreds of megahertz, while significantly decreasing the difference in thickness, which is important when calculating the permeability of the film. The temperature-frequency characteristics of the films deposited on special pidkladenkah DyScO3, SmScO3, LSAT, for nanoscale strained films. The results obtained are in good agreement with the theoretically prescribed characteristics and measurements by other known methods of research.
