Experimental investigation of dielectric characteristics of curvilinear samples of material.
View through CrossRef
The method of measuring the dielectric characteristics (ε, tg δ) of curvilinear samples of a dielectric material using volume adjustable resonator is proposed in that paper. Experimental researches were carried out by using resonant cavity, which proof the receiption of practical data about the dielectric characteristics of curvilinear material samples. Measurements were carried out on curvilinear samples (radius of curvature R = 100…200 mm) of following materials: fluoropolymer and perspex. Theoretical inaccuracy of measurements was estimated. The introduced method of measuring the dielectric characteristics of curvilinear samples of a dielectric material can be used for estimating of stability of the distribution of dielectric characteristics over surface of a manufactured structural component for radio-frequency engineering purpose (for example, radio transparent radome) as part of the destructive testing.
