Circuit approach to the minimal configuration of terahertz anomalous extraordinary transmission
Beruete Díaz, Miguel ; Navarro Cía, Miguel ; Kuznetsov, Sergei A.; Sorolla Ayza, Mario (American Institute of Physics, 2011) Artículo / ArtikuluaIn this letter we present an in-depth circuit analysis of anomalous extraordinary transmission ET through subwavelength slit and hole arrrays loaded by a dielectric slab. We show the key role played by the thickness of the ... -
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
Pacheco-Peña, Víctor ; Engheta, Nader; Kuznetsov, Sergei A.; Gentselev, Alexandr; Beruete Díaz, Miguel (American Physical Society, 2017) Artículo / ArtikuluaThe terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ... -
Planar holographic metasurfaces for terahertz focusing
Kuznetsov, Sergei A.; Astafev, Mikhail A.; Beruete Díaz, Miguel ; Navarro Cía, Miguel (Springer Nature, 2015) Artículo / ArtikuluaScientists and laymen alike have always been fascinated by the ability of lenses and mirrors to control light. Now, with the advent of metamaterials and their two-dimensional counterpart metasurfaces, such components can ... -
Polypropylene-substrate-based SRR- and CSRR-metasurfaces for submillimeter waves
Aznabet, Mariem; Navarro Cía, Miguel ; Kuznetsov, Sergei A.; Gelfand, A. V.; Fedorinina, N. I.; Goncharov, Yu. G.; Beruete Díaz, Miguel ; El Mrabet, O.; Sorolla Ayza, Mario (Optical Society of America, 2008) Artículo / ArtikuluaIn this paper it is presented the fabrication of low loss millimeter wave metamaterials based on patterning on polypropylene substrates by conventional contact photolitography. We study numerically and experimentally ... -
Regular and anomalous extraordinary optical transmission at the THz-gap
Kuznetsov, Sergei A.; Navarro Cía, Miguel ; Kubarev, V. V.; Gelfand, A. V.; Beruete Díaz, Miguel ; Campillo, Igor; Sorolla Ayza, Mario (Optical Society of America, 2009) Artículo / ArtikuluaIn this paper Anomalous Extraordinary Transmission (ET) is reported for s-polarization of low loss doubly periodic subwavelength hole arrays patterned on polypropylene (PP) substrates by conventional contact photolithography ... -
Wide angle terahertz sensing with a cross-dipole frequency selective surface
Rodríguez Ulibarri, Pablo ; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (AIP Publishing, 2016) Artículo / ArtikuluaIn 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 ...
