Abstract
Passive optical and coaxial microwave structures with periodical heterogeneities: sensor technologies transfer
Incoming article date: 28.09.2016The paper discusses passive microwave structures with periodical heterogeneites in the coaxial cable that are based on optical technologies transfer similar to the fiber Bragg structures. Among the considered: Bragg, long-period and chirped gratings, Fabry-Perot interferometer, couplers. Results and analysis of the main methods of coaxial Bragg microwave structures modeling, including the method of coupled modes and the method of directed graphs are described and discussed. Obtained spectral characteristics of these structures in their experimental implementation are presented. The main production technology of coaxial Bragg microwave structures and their impact on the specified spectral characteristics are defined. Embodiments of said microwave coaxial Bragg structures using in sensor applications are shown. In particular, we discuss the creation of mechanical strain, dielectric parameters of liquids and the level of liquid products sensors.
Keywords: Bragg microwave structures on the coaxial cable, modeling, method of directed graphs, method of coupled modes, sensor applications, deformation, dielectric permittivity, level meter
