Uniaxial dielectric mediums with hyperbolic dispersion relations
Tom G. Mackay, Akhlesh Lakhtakia, Ricardo A. Depine
The dispersion relations for conventional uniaxial dielectric mediums may be characterized as elliptical or elliptical-like, according to whether the medium is nondissipative or di…
Negative phase velocity in isotropic dielectric-magnetic mediums via homogenization
Tom G. Mackay, Akhlesh Lakhtakia
We report on a strategy for achieving negative phase velocity (NPV) in a homogenized composite medium (HCM) conceptualized using the Bruggeman formalism. The constituent material p…
Plane waves with negative phase velocity in isotropic chiral mediums
Tom G. Mackay
The propagation of plane waves in an isotropic chiral medium (ICM) is investigated. Simple conditions are derived--in terms of the constitutive parameters of the ICM--for the phase…
Geometrically-Derived Anisotropy in Cubically Nonlinear Dielectric Composites
Tom G. Mackay
We consider an anisotropic homogenized composite medium (HCM) arising from isotropic particulate component phases based on ellipsoidal geometries. For cubically nonlinear component…
Negative refraction in outer space?
Tom G. Mackay, Akhlesh Lakhtakia
Mediums which do not support the propagation of plane waves with negative phase velocity (NPV) when viewed at rest can support NPV propagation when they are viewed in a reference f…
