Extraordinary THz transmission with a small beam spot: the leaky wave mechanism
(Wiley, 2018)
Artículo / Artikulua,
The 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 ...
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
(American Physical Society, 2017)
Artículo / Artikulua,
The 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 ...
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 ...
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 ...
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 ...
