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 ... -
Extraordinary THz transmission with a small beam spot: the leaky wave mechanism
Navarro Cía, Miguel ; Pacheco-Peña, Víctor ; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (Wiley, 2018) Artículo / ArtikuluaThe discovery of extraordinary optical transmission (EOT) through patterned metallic foils in the late 1990s was decisive for the development of plasmonics and cleared the path to employ small apertures for a variety of ... -
Far-field and near-field physics of extraordinary THz transmitting hole-array antennas
Camacho, Miguel; Boix, Rafael R.; Kuznetsov, Sergei A.; Beruete Díaz, Miguel ; Navarro Cía, Miguel (IEEE, 2019) Artículo / ArtikuluaDespite three decades of effort, predicting accurately extraordinary transmission through subwavelength hole arrays has proven challenging. The lack of quantitative design and modeling capability to take into account ... -
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
Jáuregui López, Irati ; Rodríguez Ulibarri, Pablo ; Urrutia Azcona, Aitor ; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (Wiley, 2018) Artículo / ArtikuluaIn this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ... -
Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries
Jáuregui López, Irati ; Rodríguez Ulibarri, Pablo ; Kuznetsov, Sergei A.; Quemada Mayoral, Carlos ; Beruete Díaz, Miguel (MDPI, 2019) Artículo / ArtikuluaThe use of metasurfaces operating in the terahertz regime as biosensor devices has attracted increased interest in recent years due to their enhanced sensitivity and more accurate detection capability. Typical designs are ... -
THz sensing with anomalous extraordinary optical transmission hole arrays
Jáuregui López, Irati ; Rodríguez Ulibarri, Pablo ; Kuznetsov, Sergei A.; Nikolaev, Nazar A.; Beruete Díaz, Miguel (MDPI, 2018) Artículo / ArtikuluaSubwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ... -
Ultrathin and high-efficiency Pancharatnam-Berry phase metalens for millimeter waves
Moreno-Peñarrubia, Alexia; Teniente Vallinas, Jorge ; Kuznetsov, Sergei A.; Orazbayev, Bakhtiyar ; Beruete Díaz, Miguel (AIP Publishing, 2021) Artículo / ArtikuluaApplying the Pancharatnam–Berry (PB) principle to half-wave plate (HWP) metasurfaces allows the manipulation of wavefronts along with the conversion of the handedness of circularly polarized incident waves by simply rotating ... -
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
Moreno-Peñarrubia, Alexia; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (IEEE, 2020) Artículo / ArtikuluaIn this communication, an ultrathin transmissive half-wave plate (HWP) based on a bi-layered zigzag metasurface operating at the lower frequency edge of the terahertz (THz) spectrum is numerically and experimentally studied. ...
