Abstract

2D problem of the diffraction of the TM cylindrical electromagnetic wave by cluster considering of two silicon carbide SiC (6H-SiC modification) cylinders is considered. Rigorous numerical procedures are used to study Plasmon resonances in such clusters. Frequency characteristics for the scattering cross section, the field distribution on the cylinder’s surface and spatial structure of the field in the vicinity of the clusters was calculated for symmetrical and nonsymmetrical excitation by the cylindrical wave, different diameters of the cylinders, distances between cylinders and loss of 6H-SiC medium. It was found two different types of Plasmon resonances are taking place in terahertz wavelength range 10.3 μm – 11.0 μm.
