When does the choice of the refractive index of a linear, homogeneous, isotropic, active, dielectric medium matter?
Akhlesh Lakhtakia, Joseph B. Geddes, Tom G. Mackay
Two choices are possible for the refractive index of a linear, homogeneous, isotropic, active, dielectric material. Either of the choices is adequate for obtaining frequency-domain…
Engineering the phase speed of surface-plasmon wave at the planar interface of a metal and a chiral sculptured thin film
Akhlesh Lakhtakia, John A. Polo
The solution of a boundary-value problem formulated for a modified Kretschmann configuration shows that the phase speed of a surface-plasmon wave guided by the planar interface of…
On metallic gratings coated conformally with isotropic negative-phase-velocity materials
Marina E. Inchaussandague, Akhlesh Lakhtakia, Ricardo A. Depine
Application of the differential method (also called the C method) to plane-wave diffraction by a perfectly conducting, sinusoidally corrugated metallic grating coated with a linear…
Negative reflection in a Faraday chiral medium
Tom G. Mackay, Akhlesh Lakhtakia
The four wavenumbers associated with planewave propagation in a Faraday chiral medium (FCM) with relatively huge magnetoelectric coupling give rise to enhanced possibilities for ne…
Electrically controlled Bragg resonances of an ambichiral electro-optic structure: oblique incidence
Mukul Dixit, Akhlesh Lakhtakia
The Pockels effect can increase the effective birefringence of ambichiral, electro--optic rejection filters made of materials with a point group symmetry, when a dc ele…
Morphological influence on surface--wave propagation at the planar interface of a metal film and a columnar thin film
Akhlesh Lakhtakia, John A. Polo
The selection of a higher vapor deposition angle when growing a columnar thin film (CTF) leads to surface-wave propagation at a planar metal-CTF interface with phase velocity of lo…
