On the refractive index for a nonmagnetic two–component medium: resolution of a controversy
نویسندگان
چکیده
The refractive index of a dielectric medium comprising both passive and inverted components in its permittivity was determined using two methods: (i) in the time domain, a finite–difference algorithm to compute the frequency–domain reflectance from reflection data for a pulsed plane wave that is normally incident on a dielectric half–space, and (ii) in the frequency domain, the deflection of an obliquely incident Gaussian beam on transmission through a dielectric slab. The dielectric medium was found to be an active medium with a negative real part for its refractive index. Thereby, a recent controversy in the scientific literature was resolved.

Negative refraction at optical frequencies in nonmagnetic two-component molecular media.
There is significant motivation to develop media with negative refractive indices at optical frequencies, but efforts in this direction are hampered by the weakness of the magnetic response at such frequencies. We show theoretically that a nonmagnetic medium with two atomic or molecular constituents can exhibit a negative refractive index. A negative index is possible even when the real parts o...
متن کاملTheoretical Calculations of Refractive Index of Synthesized One and Two Substituted Derivatives of Functionalized Bithiophene Compounds
In order to study the variation of electronic properties, a set of bithiophene derivatives has been developed. Here, the effect of substitution on the aromaticity properties of some cyclic bithiophene derivative compounds was investigated using theoretical calculations. Calculations were performed at B3LYP/6-31+G (d,p) level; and calculated properties included energy, dipole moment, total c...

متن کاملInfluence of current density on refractive index of p-type nanocrystalline porous silicon
Porous Silicon (PS) layers have been prepared from p-type silicon wafers of (100) orientation. SEM, XRD, FTIR and PL studies were done to characterize the surface morphological and optical properties of PS. The porosity of the PS samples was determined using the parameters obtained from SEM images by geometric method. The refractive index values of the PS samples as a function of poros...
