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 ... -
Super-oscillatory metalens at terahertz for enhanced focusing with reduced side lobes
Legaria Lerga, Santiago; Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (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 ...
