INFLUENCE OF THE CRYSTAL LATTICE DIELECTRIC CONSTANT OF CONDUCTIVE MEDIUM ON THE RESONANCE INTERACTION OF ELECTROMAGNETIC WAVES IN THE DEFECT PHOTONIC CRYSTAL–CONDUCTOR STRUCTURE

Abstract

The defect photonic crystals bordering on the solid-state plasma-like media are worthy of special attention. These structures are of interest due to the occurrence of the plasma and defective waves which can interact resonantly with each other. The effect of resonance interaction of different types of electromagnetic waves in defective photonic crystals is not adequately investigated. In this paper, the resonance interaction of plasma and defective TM-electromagnetic waves in a one-dimensional defect dielectric photonic crystal, bordering on the solid-state plasma-like medium, is studied on the basis of the numerical solution of the dispersion equation. The dispersive and energy properties of plasma and defective waves are investigated in accordance with the dielectric constant of the crystal lattice of the solid-state plasma-like medium. It is found that the resonance interaction of plasma and defective waves depends strongly on the type of solid-state plasma-like media. It is established that the effect of resonance interaction between the plasma and the defective waves takes place when the defective photonic crystal borders on the semiconductor plasma. It is shown that the resonance interaction of plasma and defective waves disappears in the case when the defective photonic crystal borders on metal. The results of the study extend significantly our knowledge about the nature of the resonance interaction of plasma and defective waves in defect photonic crystals. The obtained results can be used in developing new devices of microelectronics and photonics.
