Wood zone plate fishnet metalens
(EDP Sciences, 2015) Artículo / Artikulua,
Fresnel-zone plate lenses provide focusing performance while having low profile. Unfortunately, they usually display higher reflection losses than conventional dielectric lenses. Here, we demonstrate a low-profile Wood ...
Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves
(AIP Publishing, 2014) Artículo / Artikulua,
A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ...
Zoned fishnet lens antenna with reference phase for side lobe reduction
(IEEE, 2015) Artículo / Artikulua,
Reduction of first side lobe level and nulls in artificial fishnet metalenses is accomplished here by applying the reference phase concept along with the zoning technique. Higher focusing efficiency is achieved for a ...
Ultra-compact planoconcave zoned metallic lens based on the fishnet metamaterial
(AIP Publishing, 2013) Artículo / Artikulua,
A 1.5λ0 -thick planoconcave zoned lens based on the fishnet metamaterial is demonstrated experimentally at millimeter wavelengths. The zoning technique applied allows a volume reduction of 60% compared to a full fishnet ...
