Eigenwave spectra of an anisotropic cylindrical solid-state waveguide

Dispersion properties of eigenwaves of an anisotropic cylindrical solid-state waveguide without frequency dispersion in permittivity tensor components have been analyzed theoretically. The classification of waves has been performed. $E$ type bulk–surface eigenwaves with negative group velocities have been found. The conditions for their existence have been determined. The existence in the waveguide of $E$-type surface eigenwaves and pseudo-surface eigenwaves of $E$- and $H$-types has been shown.
