In the past few years, new developments in structured electromagnetic materials have given
rise to negative refractive index materials which have both negative dielectric permittivity …

Ever since the first experimental demonstration was reported in 2000, the interest in
metamaterials and left-handed media that exhibit a negative refractive index has increased …

A new generalized nonlinear Schrödinger equation describing the propagation of ultrashort
pulses in bulk media exhibiting frequency dependent dielectric susceptibility and magnetic …

Historically, the physics, energy spectrum, and wave functions of superlattices have had
different levels of understanding. Unlike the standard approaches, based on theorems for …

Modern plasmonics plays a crucial role in photonics and optics, and paves a way for a
variety of emerging applications. Since the stationary behavior of plasmonic nanoparticles is …

This paper studies the effects of the incoherent pum** field and the spontaneously
generated coherence (SGC) on the phase control of group velocity. The effects of a relative …

In this paper, the reflected and transmitted group delay from a one-dimensional photonic
crystal heterostructure with graphene at communication band are investigated theoretically …

Guided Wave Optics and Photonic Devices introduces readers to a broad cross-section of
topics in this area, from the basics of guided wave optics and nonlinear optics to …

This paper investigates the group velocity of a probe field in a four-level atomic system. It is
shown that switching from positive to negative dispersion can be achieved just by the …

We have theoretically investigated the group delay of the TE-polarized beam reflected from
a Fabry-Perot cavity with the insertion of the graphene sheets in the near-infrared band. It is …
