METHOD OF NONDESTRUCTIVE TEST OF REFLECTION COEFFICIENT OF RADIO ABSORBING POLYMERIC COMPOSITE MATERIALS
(pp. 44-48)

Abstract. This article is devoted to the research of reflection coefficient of radio absorbing polymeric composite materials (PKM) by non-destructive method. Measurements are carried out in free space and allow to carry out assessment of reflection coefficient of materials of radio engineering assignment with averaging the values on antenna aperture area, in dozens times exceeding sizes of samples in wave guides and also allows to carry out non-destructive testing directly products. Features of measurement of reflection coefficient of samples are described. The description of ambiguity of the concept “reflection coefficient” is given. The stand for monitoring procedure of reflection coefficient of materials of radio engineering assignment by non-destructive method is described. The standard sizes of samples, sufficient for reflection coefficient measurements with the different frequency ranges are described. The practical error of measurements is evaluated. Advantages of this method are described, cases of the most reasonable application are considered.

Keywords: radio absorbing material, reflection coefficient, material of radio engineering assignment, non-destructive testing.
