ABSTRACT

The defective layered periodic structures (defective photon crystals), bordering upon plasma-like media (semiconductors and metals), arouse considerable interest. This is due to the fact that in such structures there are electromagnetic waves of different types. The properties of these waves have not been adequately investigated yet. The TM-electromagnetic waves in the one-dimension defective dielectric layered periodic structure, bordering upon a plasma-like medium, are studied in this paper on the basis of the numerical solution of the dispersion equation. The dispersion and energy properties of the plasma and defective modes are investigated depending on the location of the defective layer in the layered periodic structure. The effect of the resonant interaction of plasma and defective modes is predicted. The possibility for exciting electromagnetic waves in a defective layered periodic structure by the frustrated total internal reflection is shown. The results of investigations give some ideas of the nature of propagating electromagnetic waves in defective layered periodic structures and they can be used for developing new types of the waveguide structures used in up-to-date devices of signal processing in microwave and optical wave bands.
