REFLECTOMETRE Russian patent published in 2011 - IPC G01R27/06 

FIELD: physics.

SUBSTANCE: reflectometre for measurement of reflectance of a flat set of rectangular ferritic plates contains a measuring device with a SHF radio-wave generator. The reflectometre is equipped with a conic, symmetrical, airial strip line consisting of an output coaxial connector (connected via a SHF cable to the input/output of the measuring device), a central conductor, two outer conductors and a short-circuiter. The central conductor is designed in the form of a plain isosceles triangle the height whereof is equal to the length of the strip line while its foundation width is, as a minimum, 1.6 times narrower than the major foundation of the outer conductors. The outer conductors are designed in the form of an isosceles trapezium, the length of their major foundation is equal to the length of the flat set of ferritic plates, the acute angle of the central conductor is electrically connected to the inner conductor of the SHF connecter while its foundation is rigidly and electrically connected to the short-circuiter along its longitudinal axis. The middles of the smaller foundations of the outer conductors are rigidly and electrically connected to the diametrically opposite sides of the outer conductor of the coaxial to the SHF connecter while their major foundations are rigidly and electrically connected to the major lateral sides of the short-circuiter.

EFFECT: reflectometre dimensions and weight reduction which ensures its mobility and capability of reflectance measurement by a direct method under the conditions of radar absorbent materials manufacturing.
