Autor: Gabriel de Souza Cortês, Davi Franco Rego, Luiz Antonio Pimentel Cavalcanti, Cláudia Teresa Teles Farias, Ivan Costa da Silva
Publikováno v: Concilium. 23:483-497
Metal piping in industrial plants is subject to corrosion under insulation, which reduces the wall thickness and limits service life and operating conditions. The Pulsed Eddy Current (PEC) technique can be effective in the inspection of isolated meta

Asymmetrical absorption in plasmonic devices optimized by genetic algorithms
Autor: Davi Franco Rêgo, Vitaly F. Rodriguez-Esquerre
Publikováno v: Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XVI.
Asymmetrical absorption plays an important role in applications such as photovoltaics, detectors, modulators and emitters. In this work, we introduce and numerically analyze a broadband device capable of realizing asymmetrical optical absorption depe

Wide-angle filters based on nanoresonators for the visible spectrum
Autor: I. L. Gomes de Souza, Vitaly F. Rodriguez-Esquerre, Davi Franco Rêgo
Publikováno v: Applied optics. 57(23)
We present a design for a highly efficient and omnidirectional color-selective filter for the visible spectrum, based on a Fabry–Perot metal–dielectric–metal nanoresonator. The filter can have the same color transmitted in a range of incident a

Ultra-broadband plasmonic groove absorbers for visible light optimized by genetic algorithms
Autor: Davi Franco Rêgo, I. L. Gomes de Souza, Vitaly F. Rodriguez-Esquerre
Publikováno v: Metamaterials XI.
Plasmonic groove structures, which are widely known for its absorbent properties of light, are numerically investigated. Genetic algorithms have been successfully used to aid in the design of two-dimensional high efficiency wide-angle plasmonic groov

Publikováno v: 2016 51st International Universities Power Engineering Conference (UPEC).
The connection of loads on a main power cable causes a transient signal that propagate along the lines near the speed of light. Such signal is usually named a ‘Travelling wave’. Several techniques make use of TW signals for fault location in tran
