Abstract :
This paper presents microwave NDT of exfoliation of dielectric plate consisting of two identical plates of organic glass with air-gap between them. The material is described by its thickness, permittivity and loss-angle tangent. Experimental measurement of complex reflection coefficient of electromagnetic wave from dielectric plate is also performed on the automated stand for microwave diagnostics in frequency band 58....76 GHz.
