Properties of complexly periodic inhomogeneous systems in radio and optical guiding structures

Abstract

We have considered a questions associated with the analysis of the spectral characteristics of fiber Bragg gratings and periodic radio frequency in coaxial cable systems with uniform periodic structure containing a discrete phase shift. These fiber gratings are designed for measurement of temperature, linear and bending tension and allow by 1-2 orders increase their resolution. Shows the effect of increasing the sensitivity of electrophysical parameters definition using Bragg structures with a phase shift in the coaxial cable.
