Degeneracy of low-frequency resonances in a chiral anisotropically conducting cylinder filled with a metamaterial

Degeneration of quasi-static resonances in an impedance circular cylinder covered by a metamaterial layer

“…In this study, we demonstrate that the effect of degeneration of high Q quasi static resonances also occurs in imped ance cylinders covered by a metamaterial layer. Here, we deal with a scalar diffraction problem that leads to results similar to those obtained from the solution of the vector problem studied in [8] but differs from the latter in the subject of investigation and by a simpler mathematical apparatus.…”

“…In this situation, the field is described by the only azimuthal harmonic cos(mϕ). It is shown in [8] that the effect of degeneration of quasi static resonances can be observed in a chiral anisotropically conducting cylinder filled by a metamaterial. In particular, this effect manifests itself in that the resonance field is described by the function cos(mϕ) with different val ues of index m in the near and far zones.…”
