On the Dispersion Curves of Anisotropic Waveguides

Computational Mathematics and Mathematical Physics. 2018. Vol. 58. No. 7. P. 1142-1149.
Delitsyn A.L.

Behavior of the dispersion curves of waveguides with anisotropic filling is considered. The existence of backward and complex waves at certain values of the anisotropy coefficients is established. The region of localization of the singular points of the dispersion curves in which the generation of backward waves takes place is found.
