摘要

FIELD: methods for detecting irregularities of electro-physical and geometric parameters of dielectric and magneto-dielectric covers on metal surface, possible use during control of composition and properties of solid covers in chemistry, paintwork and other industrial branches. ^ SUBSTANCE: UHF introscopy method includes creating an electromagnetic field of slow surface wave above a dielectric cover on electro-conductive substrate and following recording of electric field strength changes. Expectation malpha and dispersion Dalpha are computed for normal fading coefficient of electric field of slow surface wave in each point of measurements of the surface being scanned using provided mathematical formulas. Using a matrix of dispersion values of field fading coefficient, across the whole scanning surface a spatial distribution of normal fading coefficient of slow surface wave field is built, for which wave the spatial pattern visually shows shape and geometric dimensions of irregularities. ^ EFFECT: increased precision when determining irregularities of covers and when evaluating their geometric and electro-physical parameters. ^ 2 dwg
