Phase and reflectivity behavior near the excitation of surface plasmon polaritons in Kretschmann-ATR systems with metamaterials
(Springer, 2012-01)
In this work we study the optical response of Kretschmann-ATR structures with metamaterials near conditions of resonant coupling between the incident wave and a surface plasmon polariton. In contrast with previous research ...
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) ...
Development of a simplified light reflectance value assessment tool for indoor surface coverings
(Sage Publications Ltd, 2020-05)
Light reflectance value (LRV) of indoor surfaces impacts on electricity consumption for lighting. For this reason, inner surface reflectance is one of the parameters required by building energy efficiency codes and standards. ...
Lane Surface Identification Based on Reflectance using Laser Range Finder
(12/13/2014)
In striving to achieve autonomous navigation the problem of guidance is a major difficulty faced by fully autonomous vehicle. In this paper, the authors focus on unconventional methods of identifying lane markings on a ...
Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves
(Elsevier Science, 2019-02)
The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D ...
Design of reflectivity-based surface plasmon resonance optical sensors for ultrasound detection
(Taylor & Francis Ltd, 2021-06)
Sensors based on surface plasmon resonance present attractive features for the detection of narrow acoustic pulses since they can behave as quasi-point detectors. In order to detect fast ultrasound pressure waves, the ...
Functional surfaces through the creation of adhesion and charged patterns on azopolymer surface relief gratings
(Elsevier Science, 2019-04)
We show that an azopolymer can be used to create a supramolecular architecture in a parallel process with patterned surface properties. By illuminating with an interference pattern, we created adhesion and charge patterns ...
Fluorescence of polyaniline films on electrode surfaces: Thickness dependence and surface influence
(Elsevier Science Sa, 2009-07)
The dependence of the photoluminescence of polyaniline films, supported onto platinum or fluorine-doped SnO2 (FTO) electrodes, on the film thickness (as measured by the voltammetric charge) has been studied for different ...
Photoemission spectroscopy of planar and nanostructured surfaces
(Elsevier Science, 2016-02)
In this paper, I present some results for the process of excitation of bulk and surface plasmons during the emission of electrons in the proximity of surfaces of different shapes and dimensions. I describe in detail the ...
