Refractive index and thickness of a transparent film (ZnS) on a transparent substrate (BK-7 glass) have been determined from measurement of normal incidence transmittance, using different methods. Some of the methods considered here are most widely used, as is apparent from the literature. The...

Optical properties of InP:S single crystals were investigated using spectrophotometric measurements in the spectral range of 200–2500 nm. The absorption coefficient and refractive index were calculated. It was found that InP:S crystals exhibit allowed and forbidden direct transitions with...

The results of first-principles theoretical study of the structural, electronic and optical properties of SrCl<Subscript>2</Subscript> in its cubic structure, have been performed using the full-potential linear augmented plane-wave method plus local orbitals (FP-APW+lo) as implemented in the WIEN2k code. In this...</subscript>

Epsilon-negative (ENG) and mu-negative (MNG) materials are successfully realized by using composite right/left-handed transmission line (CRLH TL), based on which the photonic crystals were also constituted. The simulated and measured scattering parameters and phase shift indicate that the...

A first-principles study has been performed to evaluate the electronic and optical properties of wurtzite Zn<Subscript>1-x</Subscript>Mg<Subscript>x</Subscript>O. Substitutional doping is considered with Mg concentrations of x=0, 0.0625, 0.125, 0.1875 and 0.25, respectively. Mg incorporation can induce band gap widening due to the decrease...</subscript></subscript>
