Optical constants of Bi8Te7S5

Surface Science, 1969
Abstract Interrelationships between optical constants of Bi 8 Te 7 S 5 are independent of thickness, as it is shown by a comparison of thin film transmission data to thick crystal ellipsometric data.

Notes on Optical Constants

Mathematical Proceedings of the Cambridge Philosophical Society, 1925
The tensor calculus introduced in a recent paper proves a powerful method of investigating the light scattered laterally as exemplified in the blue of the sky. The late Lord Rayleigh worked out the effect on the polarisation of having non-spherical molecules, and the present note is practically a repetition of his work but with a somewhat greater ...

On the optical constants of metals

Czechoslovak Journal of Physics, 1952
Are optical constants of metals constant in the real meaning of the word or are they dependent on the angle of incidence? This paper is an introductory contribution to the solution of this problem.

Optical constants in ion-irradiated graphite

Surface and Coatings Technology, 1994
Abstract The ion-beam-induced amorphization of crystalline graphite layers was studied by using near-IR visible and near-UV reflectance spectra to obtain the real and imaginary parts of the refractive index as a function of photon energy in the range 0.5–7 eV.

Optical Constants of Germanium

Journal of Applied Physics, 1962
A check on the over-all consistency of calculated values of the optical constants n and k for Ge is obtained by using these in a dispersion relation to evaluate the free electron plasma frequency.

Effective optical constants of anisotropic materials

Applied Optics, 1980
The applicability of a technique for determining the optical constants of soil or aerosol components on the basis of measurements of the reflectance or transmittance of inhomogeneous samples of component material is investigated. Optical constants for a sample of very pure quartzite were obtained by a specular reflection technique and line parameters ...

Theory of Optical Constants

2004
In the UV—VIS spectral range the interaction of electric field with a liquid phase is important and the interaction of magnetic field with liquid can usually be neglected in most cases of practical optical metrology. The electric charges of molecules in liquids experience the coulombian interaction.

The Optical Constants of Gallium

Proceedings of the Physical Society, 1963
The complex refractive indices have been measured for the three axes of single crystals of gallium over the range 0.4 to 8.0 micrometres using a reflection method with polarized light. In the lower energy regions if the absorption is ascribed to conduction electrons the numbers taking part according to the orientation of the electric vector relative to

Optical Constants and their Measurement

1967
The optical constants of a material are numbers which describe the manner in which a plane electromagnetic wave progresses through the material. The constants, a pair for every frequency, measure the speed and the attenuation of the wave. These constants have value not only for describing the wave progress but also for their intimate relation to the ...
