Модель резонансного вихретокового преобразователя предназначенного для контроля тонких неферомагнитных пленок

Abstract

Thin non-ferromagnetic films are widely used in electronics in the form of resistive and capacitive elements of integrated circuits, devices for recording and storing information, hemotron devices, in aviation and space technology, in optics, microwave technology, used as coatings for protection against electromagnetic radiation, and also used In decorative purposes. The paper deals with the theory of resonance vibration current converters for the control of thin neferromagnetic films. The analysis of the influence of the internal resistance of the pow er supply of the converter and the parameters of the structure of thin non-ferromagnetic films on the input and output parameters and characteristics of the converter is performed. A comparison of the sensitivity of a resonant converter model with an aperiodic model is performed.
