Abstract

An impedance cylinder covered by a metamaterial layer is considered. The 2D problem of excitation of the cylinder by a magnetic-current filament is analyzed. High-Q surface-wave resonances formed in cylinders of small (as compared to the wavelength) dimensions are investigated. The effect of degeneration of oscillations with different indices m in the law cos(mφ), which describes the azimuthal dependence of resonance fields, is discovered. The spatial and frequency characteristics of degenerate oscillations are numerically investigated on the basis of rigorous methods.
