The effect of optical non-reciprocity in multilayer nanostructure systems based on Bi

In multilayer non-magnetic structures with island layers Bi ([Bi-Al 2 O 3 ] N --- at room temperature, an abnormally large optical non-reciprocity effect was detected. It is shown that this can be closely related to the behavior of dielectric permittivity in nanostructured layers. found these systems, metallic nature response constant (Re(ε)<0) observed <0) range when thickness layer Al less than 1.6 nm. assumed systems [Bi-Al exhibit properties "left" metamaterials negative μ and ε range.
