Influence of the sign of the refractive index in the reflectivity of a metamaterial surface with localized roughness
(Springer, 2011-06)
To study the scattering properties of metamaterials, we generalize two scattering methods developed for conventional (non-magnetic) isotropic materials to the case of materials with arbitrary values (positive or negative) ...
Dispersive characteristics of surface plasmon polaritons on negative refractive index gratings
(Elsevier Science, 2011-10)
The dispersive characteristics of surface plasmon polaritons (SPPs) supported by a periodically corrugated boundary between vacuum and a negative refractive index, isotropic material were studied theoretically by numerical ...
Optical quality mesoporous alumina thin films
(Elsevier Science, 2019-10)
A robust method for the preparation of optical-quality mesoporous alumina thin films is presented, using evaporation induced self assembly of triblock copolymer surfactants. The use of lowly reactive aluminium chloride as ...
Combination of guided mode and photometric optical metrology methods for precise determination of refractive index dispersion: application to polymer blend and ceramic thin films for gas sensors
(International Society for Optical Engineering - SPIEBellingham, 2013-09)
Two optical techniques, m-lines and spectroscopic ellipsometry, are compared for their suitability for obtaining the wavelength and the temperature dispersion of the refractive index of thin-film layers used in gas detector ...
Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...

Optically pump-induced athermal and nonresonant refractive index changes in the reference Cr-doped laser materials: Cr:GSGG and ruby
(Optical Society of America - OSAWashington, DC, 2012-05)
The refractive index of most ion-doped materials increases with the excited state population. This effect was studied in many laser materials, particularly those doped with 'Cr POT. 3+' and rare earth ions, using several ...
Design of high-oleic palm oil nanoemulsions suitable for drying in refractance window™Diseño de nanoemulsiones de aceite de palma alto oleico aptas para secado en refractance window™
(Journal of Food Processing and Preservation, 18/11/2020)
Nanoencapsulation is a technique in which high-interest lipids are protected. Refractance Window™ is a novel drying technique designed mainly to convert fruit puree into powder, flakes, or concentrates. Thus, in this work ...
