Negative refraction, negative phase velocity, and counterposition
Tom G. Mackay, Akhlesh Lakhtakia
The planewave response of a linear passive material generally cannot be characterized by a single scalar refractive index, as directionality of energy flow and multiple wavevectors…

Spectral shifts in the properties of a periodic multilayered stack due to isotropic chiral layers
S. Anantha Ramakrishna, Akhlesh Lakhtakia
Investigating the canonical problem of a periodic multilayered stack containing isotropic chiral layers, we homogenized it as a uniaxial bianisotropic medium and derived its effect…

On the application of homogenization formalisms to active dielectric composite materials
Tom G. Mackay, Akhlesh Lakhtakia
The Maxwell Garnett and Bruggeman formalisms were applied to estimate the effective permittivity dyadic of active dielectric composite materials. The active nature of the homogeniz…
