Localized monochromatic and pulsed waves in hyperbolic media
Consider a uniaxially anisotropic material with diagonal electric permittivity and magnetic permeability tensor elements εxx, εyy = εxx, εzz and μxx, μyy = μxx, μyy, respectively. If all four elements are positive, the dispersion relation is described by an ellipsoid. Within a certain frequency band, however, it may turn out that not all diagonal elements are positive and the dispersion relation is a hyperboloid. Under these conditions, the material is referred to as a hyperbolic medium. For simplicity, the discussion will be confined to a nonmagnetic material. Source-free, transverse magnetic electromagnetic fields in the frequency domain are expressed in terms of an appropriately defined Hertz vector potential equation governed by the equation © 2013 IEEE.
