Sensor applications of Bragg microwave structures realized in coaxial waveguide

Abstract

The Bragg microwave structures on the coaxial waveguide, constructed on the basis of the transfer optical technologies similar to the Bragg fiber grating, are considered. It is offered to use versions of such coaxial Bragg microwave structures in sensor application, in particular, creation of strain gauges, instruments for measuring dielectric constant of liquids and liquid products' level is considered. Methods for description of periodic inhomogeneous microwave structures characteristics and ways to modify the form of the frequency dependence of scattering parameters are viewed.
