Sub-picosecond Z-scan measurements of the nonlinear refractive index of dense materials We present the results of Z-scan studies on a new setup in the sub-picosecond regime (central wavelength 800 nm) carried out on solid and liquid materials ... F Billard,M Commre,C Amra,... - Laser-...
B. MOLAR REFRACTION The molar refraction of a substance, a product of its refractive index, molecular weight, and density, may be assumed to be a fundamental physical property of materials (1). Furthermore, the molar refraction may be treated (as established by Denbigh) as the sum of the...
Modern materials engineering—particularly the concept of metamaterials—has made it necessary to consider its subtleties, including anisotropy and complex values. Here we re-examine the refractive index and find a general way to calculate the direction-dependent refractive index and the condition for ...
Moreover, the technique is presented in a simple way with a view to applying and reviewing the concepts of internal reflections occurring in a thin piece of material (substrate). 关键词: Refractive index determination of materials on thin transparent substrates using ellipsometry, Artículo DOI: ...

Novel hyper-branched, dense, high-refractive-index polymers, and compositions utilizing those polymers are provided, along with methods of forming high refractive index films with those compositions. The refractive index of the material is at least about 1.8 at 400 nm. Further, it can be made ...
Models are presented which describe the refractive index and spectral variation of gradient-index materials. Classes of gradient which exhibit little or no variation with wavelength are predicted. These are termed achromatic gradients. Experimental verification of the models is presented in a following pa...
A simple method of measuring refractive indices of bulk materials using a prism coupling procedure is described. Refractive indices are determined from the measurement of the angle incident to the prism at which total reflection on the prism base breaks. This method is shown to possess the advantag...
