Electrodynamic properties of dielectric lattices infrared wavelength resonators
Main Article Content
Abstract
The investigation results of the new kind of materials that are the finite dimensions periodic structures of Dielectric Resonators (DR) are presented. Some of the structure properties do not have natural analogues and are not studied completely yet. The gratings containing cylindrical shape DRs with magnetic type characteristic oscillations located in the metal plane regular waveguide are studied. For the determination of the key parameters such as complex resonance frequencies and partial DR amplitudes, the developed earlier electrodynamics model based on the application of the perturbation theory for Maxwell equations is used. The obtained theoretical results demonstrate the possibility to develop resonators of a new type having a high value of Q-factor and divided by frequency band from another coupled oscillations. The research results of the plane wave scattering on cylindrical DR grating in the open space are presented.
