Dispersion characteristics of planar dielectric waveguide - grating system

Abstract

In this work, the results of theoretical and experimental study of eigen waves of periodical system formed of planar dielectric waveguide and grating are presented. The research revealed the dispersion characteristic features that helps to understand the resonant effects which occur during the radiation forming. Moreover, the results ensure an optimization of system parameters that provides the obtaining of specific characteristics of diffraction radiation antennas.
