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…

Enhanced group velocity in metamaterials
T. G. Mackay, A. Lakhtakia
The Bruggeman formalism is implemented to estimate the refractive index of an isotropic, dielectric, homogenized composite medium (HCM). Invoking the well--known Hashin--Shtrikman…

A limitation of the Bruggeman formalism for homogenization
T. G. Mackay, A. Lakhtakia
The Bruggeman formalism provides an estimate of the effective permittivity of a particulate composite medium comprising two component mediums. The Bruggeman estimate is required to…
