FIELD: means of control. ^ SUBSTANCE: method and device can be used for inspecting composition and properties of liquid and hard coatings in chemical industry, paint film industry and other branches of industry. According to the method, electromagnet microwave field is generated in bulk of inspected material and changes in parameters of converter are registered which parameters characterize microwave field. Electric field intensity attenuation is measured at normal plane relatively direction of propagation of slow surface waves. Lateral ferromagnetic resonance permanent field is created; system of equations, given in the description, is subject to solving; complex values of dielectric and magnetic permeability are determined and value of wave resistance id calculated. Slow surface wave excitation device has several horn radiators. Precision of measurements is improved due to measurement of imaginary part of dielectric and magnetic permeability. ^ EFFECT: improved precision of measurement; improved precision of measurement of wave resistance of dielectric and magnetic-dielectric coatings. ^ 2 cl, 4 dwg |
