Super-oscillatory metalens at terahertz for enhanced focusing with reduced side lobes
(MDPI, 2018)
Artículo / Artikulua,
In this paper, we design and numerically demonstrate an ultra-thin super-oscillatory metalens with a resolution below the diffraction limit. The zones of the lens are implemented using metasurface concepts with hexagonal ...
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 ...
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
(MDPI, 2020)
Artículo / Artikulua,
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
