Complex media characterized by chirality and negative refractive index

At a planer interface between free space and chiral media, Generalized Snell's law is satisfied. Moreover at a planer interface between free space and chiral media the relationship between the incident and the linearly polarized reflected electric fields in free space, is given by the reflection coefficient matrix whose diagonal terms are the familiar Fresnel reflection coefficients for the vertically and horizontally polarized waves. The off diagonal cross polarized reflection coefficients (which are zero for non chiral media) are equal to the product of the vertically and horizontally polarized transmission coefficients, (across the interface in opposite directions) the chiral parameter and the wave number of the host medium below the free space-chiral media interface. Using a complete modal expansion of the Green's function associated with the problem, it is shown that the full wave species include evanescent and propagating radiation fields, several types of lateral waves (propagating parallel to the interface) associated with the phenomena of total internal "backward" reflection as well as several different surface waves (plasmons) associated with the residues at the poles of the reflection coefficients. Thus for instance, using negative refractive index materials with chiral properties (CNRI) materials it is possible to fabricate rectangular slabs that perform as lenses associated with two focal planes at the opposite side of the source. Furthermore the lateral waves, associated with total internal "backward" reflected waves could be used to make the CNRI materials perform like reflectors (with images at the same side as the source).
