On the inapplicability of a negative-phase-velocity condition as a negative-refraction condition for active materials
A. Lakhtakia, T. G. Mackay, J. B. Geddes
A negative-phase-velocity condition derived by Depine and Lakhtakia [Microwave Opt Technol Lett 41 (2004) 315] for isotropic, homogeneous, passive, dielectric-magnetic materials is…
The homogenization of orthorhombic piezoelectric composites by the strong-property-fluctuation theory
Andrew J. Duncan, Tom G. Mackay, Akhlesh Lakhtakia
The linear strong--property--fluctuation theory (SPFT) was developed in order to estimate the constitutive parameters of certain homogenized composite materials (HCMs) in the long-…
Semiconductor split-ring resonators for thermally tunable, terahertz metamaterials
Jiaguang Han, Akhlesh Lakhtakia
As the variation of temperature alters the intrinsic carrier density in a semiconductor, numerical simulations indicate that the consequent variation of the relative permittivity i…
The Huygens principle for a uniaxial dielectric-magnetic medium with gyrotropic-like magnetoelectric properties
Tom G. Mackay, Akhlesh Lakhtakia
The dyadic Green functions for a uniaxial dielectric-magnetic medium, together with a reversible field transformation, were implemented to derive a formulation of the Huygens princ…
Total internal reflection of evanescent plane waves
Akhlesh Lakhtakia, Tom G. Mackay
Describing the phenomenon of total internal reflection in terms of a reflection coefficient of unit magnitude, we found that, not only can propagating plane waves be total internal…
Porosity Effect on Surface Plasmon Resonance from Metallic Sculptured Thin Films
Ibrahim Abdulhalim, Akhlesh Lakhtakia, Amit Lahav +2
When a sculptured thin film (STF), made of a metal and nm thick, is used in lieu of a dense layer of metal in the Kretschmann configuration, experimental data for an STF c…
