Photonic band gap (PBG) materials are periodic dielectric structures that forbid propagation
of electromagnetic waves in a certain frequency range. They are able to engineer the most …

In order to demonstrate the modulation of terahertz wave propagation in atmospheric
pressure microplasmas, in this work, the band structure and the transmission characteristics …

We present a detailed study of the full photonic band gaps for the spherical multilayered
core-shell particles arranged in bcc, fcc, and diamond fcc lattices. We find that layered …

Dielectric studies with characteristics of a photonic crystal and a new expression of Lamb
Shift including spatial average of dielectric constant for the material and its surrounding for …

Last decade has been increasing interest in metamaterial research, however metamaterials
are sometimes regarded as left handed materials (LHM) or negative index materials but the …

A new paradigm has emerged exhibiting reverse electromagnetic properties. Novel
composite and micro-structured materials (metamaterials) have been designed to control …

In recent years photonic crystals have become a favored area of research due to their
diversified applications. In this paper we propose a mathematical model for analyzing the …

We report theoretical concepts and experimental verification for three-dimensional photonic
crystal. The occurrence of photonic band gap, tunability and mechanism are given. We have …

Mechanism of occurrence of Photonic Band Gap (PBG) is presented for 3-D structure using
close packed face centered cubic lattice. Concepts and our work, specifically optical …

Studies of anomalous Lamb shift in 2p/sub 1/2/state of hydrogen for photon-atom interaction
as a function of relative dispersion frequency, refractive index contrast and propagation …
