We analyse and compare the effects of the spatial dispersion and structural anisotropy on the spectrum of a metamaterial slab. Dielectric function of the slab we describe within Drude-Lorentz approximation. Anisotropy is of the slab is introduced through the anisotropy of plasma frequencies corresponding to the different component of the permittivity tensor. Spatial dispersion is considered within...
We analyze spectrum of waveguide modes of an arbitrary uniaxial anisotropic metamaterial slab with non-local electromagnetic response whose permittivity tensor could be described within Drude approximation. Spatial dispersion was introduced within the hydrodynamical model. Both anisotropy and spatial dispersion were considered as perturbations. Spatial dispersion is shown to result in suppression...
