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 ...
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 ...
