Metamaterials and their application in the performance enhancement of reconfigurable antennas: a review
(MDPI, 2023)
Artículo / Artikulua,
Metamaterials exhibit properties in terms of subwavelength operation or phase manipulation, among others, that can be used in a variety of applications in 5G communication systems. The future and current 5G devices demand ...
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 ...
