Abstract
We investigate the general dispersion relationship of anisotropic media theoretically. According to the dispersion relationship, we study the perfect imaging conditions by a slab of anisotropies negative refractive index media in details, Numerical results have proved our predictions for TE waves. For slab of gyrotroptic media, if a gyrotroptic parameter is small enough, the gyroteoptic slab can become nearly perfect lens using the perfect conditions of TE and TM mixed modes. We have shown that perfect imaging cannot occur in the case of larger gyrotroptic parameter.
