Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
(Wiley, 2018)
Artículo / Artikulua,
In 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 ...
THz sensing with anomalous extraordinary optical transmission hole arrays
(MDPI, 2018)
Artículo / Artikulua,
Subwavelength 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 ...
Angle-susceptible sensing metasurface in terahertz regime
(EDP Sciences, 2018)
info:eu-repo/semantics/conferenceObject,
Nowadays thin-film coatings and structures are widely used in advanced industrial and scientific ap-plications that makes the tasks of thin-film sensing highly demanded in practice. Last decade, stimulated by progress in ...
Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries
(MDPI, 2019)
Artículo / Artikulua,
The 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 ...
Ultrathin and high-efficiency Pancharatnam-Berry phase metalens for millimeter waves
(AIP Publishing, 2021)
Artículo / Artikulua,
Applying 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 ...
Revealing the underlying mechanisms behind TE extraordinary THz transmission
(Chinese Laser Press, 2020)
Artículo / Artikulua,
Transmission through seemingly opaque surfaces, so-called extraordinary transmission, provides an exciting plat- form for strong light–matter interaction, spectroscopy, optical trapping, and color filtering. Much ofthe ...
Far-field and near-field physics of extraordinary THz transmitting hole-array antennas
(IEEE, 2019)
Artículo / Artikulua,
Despite 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 ...
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
(IEEE, 2020)
Artículo / Artikulua,
In 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. ...
Labyrinth absorber based on metageometries metasurface for fungi detection
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper a labyrinth metasurface based in the new paradigm of metageometries is designed to operate in the Terahertz (THz) band as a biosensor. First, a numerical study is carried out to study the performance of the ...
