Annular apertures in metallic screens as extraordinary transmission and frequency selective surface structures
Rodríguez Ulibarri, Pablo
; Navarro Cía, Miguel ; Rodríguez Berral, Raúl; Mesa, Francisco; Medina, Francisco; Beruete Díaz, Miguel (IEEE, 2017)
Artículo / Artikulua 
A 2-D periodic array of annular apertures (or ring slots) is studied using an accurate circuit model. The model accounts for distributed and dynamic effects associated with the excitation of high-order modes operating above ... -
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
Rodríguez Ulibarri, Pablo ; Crépin, Thomas; Martel, Cédric; Boust, Fabrice; Falcone Lanas, Francisco Javier ; Loecker, Claudius; Herbertz, Kai; Bertuch, Thomas; Dousset, Thierry; Martinaud, Jean-Paul; Maci, Stefano; Marcotegui, José Antonio ; Beruete Díaz, Miguel (EDP Sciences, 2016)
Artículo / Artikulua
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation ... -
Frozen mode from hybridized extraordinary transmission and Fabry-Perot resonances
Beruete Díaz, Miguel ; Rodríguez Ulibarri, Pablo ; Pacheco-Peña, Víctor ; Navarro Cía, Miguel ; Serebryannikov, Andriy E. (American Physical Society, 2013)
Artículo / Artikulua
Frozen modes arising in stacked subwavelength hole arrays are studied in detail. Their origin is proved to be connected with the interaction between the extraordinary transmission resonance and the Fabry–Perot cavity mode. ... -
Growth in the number of references in engineering journal papers during the 1972-2013 period
Úcar Marqués, Iñaki; López Fernandino, Felipe; Rodríguez Ulibarri, Pablo ; Sesma Sánchez, Laura ; Urrea Micó, Verónica ; Sevilla Moróder, Joaquín (Springer, 2014)
Artículo / Artikulua
The number of references per paper, perhaps the best single index of a journal’s scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering ... -
Hedgehog subwavelength hole arrays: control over the THz enhanced transmission
Navarro Cía, Miguel ; Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel (Institute of Physics Publishing, 2013)
Artículo / Artikulua
By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or ... -
Impact of high power interference sources in planning and deployment of wireless sensor networks and devices in the 2.4 GHz frequency band in heterogeneous environments
López Iturri, Peio ; Nazábal Urriza, Juan Antonio ; Azpilicueta Fernández de las Heras, Leyre ; Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel ; Fernández Valdivielso, Carlos ; Falcone Lanas, Francisco Javier (MDPI, 2012)
Artículo / Artikulua
In this work, the impact of radiofrequency radiation leakage from microwave ovens and its effect on 802.15.4 ZigBee-compliant wireless sensor networks operating in the 2.4 GHz Industrial Scientific Medical (ISM) band is ... -
Mid-infrared plasmonic inductors: enhancing inductance with meandering lines
Torres Landívar, Víctor; Ortuño Molinero, Rubén ; Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel ; Sorolla Ayza, Mario ; Griol, Amadeu; Martínez, Alejandro; Navarro Cía, Miguel (Nature Publishing Group, 2014)
Artículo / Artikulua
We present a mid-infrared inductor that when applied to an extraordinary transmission hole array produces a strong redshift of the resonant peak accompanied by an unprecedented enlargement of the operation bandwidth. The ... -
Nonbianisotropic complementary split ring resonators as angular selective metasurfaces
Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel (Optical Society of America, 2017)
Artículo / Artikulua
In this work, a metasurface with unconventional angular performance and composed by a nonbianisotropic complementary split ring resonator (NB-CSRR) is analyzed numerically and experimentally. A numerical study comparing ... -
One-way quasiplanar terahertz absorbers using nonstructured polar dielectric layers
Rodríguez Ulibarri, Pablo ; Serebryannikov, Andriy E.; Beruete Díaz, Miguel (American Physical Society, 2017)
Artículo / Artikulua
A concept of quasiplanar one-way transparent terahertz absorbers made of linear isotropic materials is presented. The resulting structure consists of a homogeneous absorbing layer of polar dielectric, GaAs, a dispersion-free ... -
Terahertz epsilon-near-zero graded-index lens
Torres Landívar, Víctor; Pacheco-Peña, Víctor ; Rodríguez Ulibarri, Pablo ; Navarro Cía, Miguel ; Beruete Díaz, Miguel ; Sorolla Ayza, Mario ; Engheta, Nader (Optical Society of America, 2013)
Artículo / Artikulua
An epsilon-near-zero graded-index converging lens with planar faces is proposed and analyzed. Each perfectly-electric conducting (PEC) waveguide comprising the lens operates slightly above its cut-off frequency and has ... -
Wide angle terahertz sensing with a cross-dipole frequency selective surface
Rodríguez Ulibarri, Pablo ; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (AIP Publishing, 2016)
Artículo / Artikulua
In this work, a terahertz sensor based on a cross dipole frequency selective surface is analyzed and experimentally tested. The sensing structure is optimized for operation at the fundamental band- stop resonance near ... -
Wideband backscattering reduction at terahertz using compound reflection grating
Orazbayev, Bakhtiyar ; Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel (Optical Society of America, 2017)
Artículo / Artikulua
Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ... -
Wideband unidirectional transmission with tunable sign-switchable refraction and deflection in nonsymmetric structures
