The double-indexed geometric phase for electromagnetics

Akhlesh Lakhtakia, Tom G. Mackay

The double-indexed geometric phase (DIGP) based on a family of Poincaré spinors was formulated to extend the Pancharatnam phase, commonly used to describe the evolution of the pola…

Gaussian pulse scattering by a chiral spherical shell

Hector M. Iga-Buitron, Tom G. Mackay, Akhlesh Lakhtakia

Theory was formulated for scattering by a coated chiral sphere of a plane wave of arbitrary polarization state with amplitude modulated by a Gaussian pulse. The spherical core and…

Electromagnetic homogenization of particulate composite materials comprising spheroids and truncated spheroids with orientational distribution

Héctor M. Iga-Buitrón, Tom G. Mackay, Akhlesh Lakhtakia

Implementations of the Bruggeman and Maxwell Garnett homogenization formalisms were developed to estimate the relative permittivity dyadic of a homogenized composite material (HCM)…

Anisotropic homogenized composite mediums arising from truncated spheres, spheroids, and ellipsoids

Tom G. Mackay, Akhlesh Lakhtakia

Closed-form expressions were recently derived for depolarization dyadics for truncated spheres and truncated spheroids, and the formalism was extended to truncated ellipsoids. Thes…

Depolarization dyadics for truncated spheres, spheroids, and ellipsoids

Tom G. Mackay, Akhlesh Lakhtakia

Depolarization dyadics play a central role in theoretical studies involving scattering from small particles and homogenization of particulate composite materials. Closed-form expre…

Thermal hysteresis in amplification and attenuation of surface-plasmon-polariton waves

Tom G. Mackay, Tran Vinh Son, Alain Haché +1

The propagation of surface-plasmon-polariton (SPP) waves at the planar interface of a metal and a dielectric material was investigated for a dielectric material with strongly tempe…
