Quasi-confined ENZ mode in an anisotropic uniaxial thin slab

Guided-to-Leaky Mode Transition in Uniaxial Optical Slab Waveguides

The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial crystals such as LiNbOs or LiTaOs is analyzed. Two different guided-to-leaky transitions have been identified, namely the ordinary cutoff and the extraordinary cut08 which occur when considering negative and positive birefringent materials, respectively. Analytical but transcendental expressions have been obt...

Plasmon mode characteristics of metallic nanowire in uniaxial anisotropic dielectric.

The plasmon mode characteristics of metallic nanowire embedded in a uniaxial anisotropic dielectric are investigated theoretically. The hybrid plasmon modes found in this structure are significantly different from the traditional plasmon modes of metallic nanowire in a homogeneous isotropic dielectric. In contrast to the transverse-magnetic-like wave for a traditional fundamental mode, the hybr...

3D Thermoelastic Interactions in an Anisotropic Lastic Slab Due to Prescribed Surface Temparature

The present paper is devoted to the determination of displacement, stresses and temperature from three dimensional anisotropic half spaces due to presence of heat source. The normal mode analysis technique has been used to the basic equations of motion and generalized heat conduction equation proposed by Green-Naghdi model-II [1]. The resulting equation are written in the form of a vector –matr...

Backward Wave Propagation of a Uniaxial Anisotropic -Negative Slab Composed of Metallic Spirals

1. Introduction It has been theoretically shown that backward waves can be supported not only by double-negative materials with simultaneous negative permittivity and permeability [1] but also by uniaxial anisotropic single-negative slabs with a negative component of permittivity or permeability tensor [2]. The uniaxial anisotropic single-negative materials are potentially advantageous in row l...
