Gómez-Tejedor, José-Antonio; Oset, E. (Elsevier, 1994-05-09)[EN] We have studied the gammap--> pi+ pi- p reaction using a model which includes N, DELTA(1232), N*(1440) and N*(1520) intermediate baryonic states and the rho-meson as intermediate 2pi-resonance. The model reproduces ... -
Sánchez-Dehesa Moreno-Cid, José; Torrent, Daniel; Cai, Liang - Wu (IOP Publishing: Open Access Journals, 2009-01-23)Acoustic transparency is studied in two-dimensional sonic crystals consisting of hexagonal distributions of cylinders with continuously varying properties. The transparency condition is achieved by selectively closing the ... -
Garín Escrivá, Moisés; Fenollosa Esteve, Roberto; Alcubilla, Ramón; Shi, Lei; Marsal, L. F.; Meseguer Rico, Francisco Javier (Nature Publishing Group, 2014-03)[EN] Silicon is the material of choice for visible light photodetection and solar cell fabrication. However, due to the intrinsic band gap properties of silicon, most infrared photons are energetically useless. Here, we ... -
Ardid Ramírez, Miguel; Felis-Enguix, Iván; Martínez Mora, Juan Antonio; Saldaña-Coscollar, María; Albert, A.; Andre, M.; Anghinolfi, M.; Anton, G.; Aubert, J. -J.; Avgitas, T.; Baret, B.; Barrios-Martí, J.; Basa, S.; Bertin, V.; Biagi, S. (Springer, 2017-06-21)A novel algorithm to reconstruct neutrino-induced particle showers within the ANTARES neutrino telescope is presented. The method achieves a median angular resolution of 6º, for shower energies below 100 TeV. Applying this ... -
Romero García, Vicente; Sánchez Pérez, Juan Vicente; García Raffi, Luis Miguel (IOP Publishing: Hybrid Open Access, 2011)The use of sonic crystals (SCs) as environmental noise barriers has certain advantages from both the acoustical and the constructive points of view with regard to conventional ones. However, the interaction between the SCs ... -
González Salido, Nuria (Universitat Politècnica de València, 2012-02-17)El estudio numérico de la dispersión de ondas planas de sonido por diferentes geometrías finitas es presentado. La información contenida en los ecos (amplitud y fase) permite caracterizar ciertas propiedades de los dispersores ... -
Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (IOP Publishing: Open Access Journals, 2008-02-06)We show that specially designed two-dimensional arrangements of full elastic cylinders embedded in a nonviscous fluid or gas define ( in the homogenization limit) a new class of acoustic metamaterials characterized by a ... -
Manjón, Francisco-Javier; Gallego-Parra, Samuel; Rodríguez Hernández, Plácida; Muñoz, Alfonso; Drasar, Cestmir; Muñoz-Sanjosé, Vicente; Oeckler, Oliver (The Royal Society of Chemistry, 2021-05-21)[EN] Two anomalous broad bands are usually found in the Raman spectrum of bulk and 2D Te-based chalcogenides, which include binary compounds, like ZnTe, CdTe, HgTe, GaTe, GeTe, SnTe, PbTe, GeTe2, As2Te3, Sb2Te3, Bi2Te3, ... -
Samaniego, Diego; Vidal Rodriguez, Borja (Institute of Electrical and Electronics Engineers, 2019-03-15)[EN] A technique to enhance the slope of a photonic microwave filter based on the stimulated Brillouin scattering is proposed. It relies on exploiting the polarization dependence of Brillouin gain in birefringent fibers. ... -
Chin, Sanghoon; Thevenaz, Luc; Sancho Durá, Juan; Sales Maicas, Salvador; Capmany Francoy, José; Berger, Perrine; Bourderionnet, Jerome; Dolfi, Daniel (Optical Society of America: Open Access Journals, 2010-10-11)[EN] We experimentally demonstrate a novel technique to process broadband microwave signals, using all-optically tunable true time delay in optical fibers. The configuration to achieve true time delay basically consists ... -
Fuente Herraiz, David (Universitat Politècnica de València, 2019-06-28)La presente tesis doctoral, titulada "Contribution to the modelling of the light field distribution within Synechocystis sp. PCC 6803 cultures and its influence on cellular photosynthesis processes", engloba diversos ... -
Zoireff, Gustavo; Samaniego, Diego; Vidal Rodriguez, Borja (Institute of Electrical and Electronics Engineers, 2021-04)[EN] A new photonic technique to implement both stopband and passband microwave filters is presented and demonstrated. The principle of operation relies on controlling the state of polarization of the band of interest using ... -
Sánchez-Dehesa Moreno-Cid, José; Gao, Penglin; Cervera Moreno, Francisco Salvador; Broatch, A.; GARCIA TISCAR, JORGE; Felgueroso-Rodríguez, Andrés (American Institute of Physics, 2022-02-28)[EN] This Letter reports the feasibility of a structure specifically designed for the control of flexural waves propagating in thin perforated plates. The structure, here denominated as a redirector device, consists of a ... -
Ibánez, J.; Oliva, R.; Manjón Herrera, Francisco Javier; Segura, A.; Yamaguchi, T.; Nanishi, Y.; Cuscó, R.; Artús, L.
