THE RESONANT INTERACTION OF ELECTROMAGNETIC WAVES IN A DEFECTIVE DIELECTRIC PERIODIC LAYERED STRUCTURE PLACED IN A PARALLEL-PLATE WAVEGUIDE
摘要
The study of the defective periodic layered structures bordering upon plasma-like media has attracted interest recently. This is due to the fact that in such structures there are the surface and bulk electromagnetic waves interacting resonantly. The effect of resonant interaction in defective periodic layered structures is not sufficiently studied. In the paper the resonant interaction of surface and bulk TM-electromagnetic waves in the one-dimensional defective dielectric periodic layered structure placed in a parallel-plate waveguide is investigated on the basis of a numerical solution of the dispersion equation. The dispersion and energy properties of the plasma and bulk modes are studied in accordance with the location of the defective layer in the periodic structure. It is shown that the peculiarities of the resonant interaction of the plasma and bulk waves essentially depend on the geometric configuration of the defective periodic layered structure. The results of our investigations expand considerably the knowledge about the nature of the resonant interaction of electromagnetic waves in defect periodic layered structures. They can be used in developing new models of radiophysical devices for the signal processing in microelectronics and photonics.
