Aperiodic Metal-Dielectric Multilayers as Highly Efficient Sunlight Reflectors
(Wiley, 2017-05-03)
The optimum reflection of the solar spectrum at well-defined incident directions as well as its durability in time are, both, fundamental requirements of the optics of thermosolar and photovoltaic energy conversion systems. ...

Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
(Elsevier, 2020-06)
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies both outside (below and above) and ...

Discrete breathers collisions in nonlinear Schrödinger and Klein-Gordon lattices
(2008)
Collisions between moving localized modes (moving breathers) in non- integrable lattices present a rich outcome. In this paper, some features of the interaction of moving breathers in Discrete Nonlinear Schrödinger and ...

MIS 5 sea-level markers and regional uplifting in the Strait of Gibraltar (North of Morocco)
(Sociedad Geológica de España, 2012)
This study investigates the morpho-sedimentary evidence of two highstands registered and dated during MIS 5 stage by U-series dating in the North of Morocco (Strait of Gibraltar). Bioerosive notch and mixed siliciclastic ...

Software de dominio público: una alternativa de coste cero para la docencia
(Universidad de Las Palmas de Gran Canaria, Servicio de publicaciones y producción documental, 1998)
En la actualidad, la necesidad de la utilización de los ordenadores como soporte fundamental para la docencia se ha hecho evidente. Ello se debe tanto a la implantación de estas máquinas en entorno empresarial ...

Radiometric dating of recent sediments: On the performance of 210 Pb based CRS chronologies under varying rates of supply
(Elsevier, 2019)
Radiometric dating was a revolutionary contribution to the study of sedimentary processes. Empirical data from varved sediments show that unsupported 210Pb (210 Pbexc) fluxes vary over time while they statistically ...

Nonlinear Schrödinger solitons oscillate under a constant external force
(2013)
We investigate the dynamics of solitons of the cubic nonlinear Schrödinger equation with an external time-independent force of the form f(x)=rexp(−iKx). Here the solitons travel with an oscillating velocity and all other ...

Physical Optics Applied to Parallel-Plate Lens Antennas
(Institute of Electrical and Electronics Engineers, 2023-12)
The Physical Optics (PO) method is used to derive simplified expressions to compute the radiation electric fields of planar graded-index and geodesic lenses based on a parallel-plate waveguide (PPW) implementation. If the ...
