Eigen Modes of Dielectric Layer - Ribbon Diffraction Grating Electrodynamic System
ABSTRACT
The problem of eigen electromagnetic waves propagation along the planar dielectric waveguide (PDW), which is electrodynamically connected with ribbon diffraction grating (RDG) is investigated. The calculation dependences of propagation constants for lower modes upon the parameters of the system are provided. Amplitude distributions of field components in transverse cross-section are calculated and built. It is demonstrated that there exist eigen modes of surface wave propagation localized in the plane of diffraction grating within the PDW - RDG electrodynamic system. The existence of hybrid modes in this system is proved. It is revealed the domain of the frequency parameter, within which the strong electrodynamic connection of the system with the free space is originated.
