Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves

Pacheco-Peña, Víctor ; Orazbayev, Bakhtiyar ; Beaskoetxea Gartzia, Unai ; Beruete Díaz, Miguel ; Navarro Cía, Miguel (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. ...
ε-near-zero (ENZ) graded index quasi-optical devices: steering and splitting millimeter waves

Pacheco-Peña, Víctor ; Torres Landívar, Víctor ; Beruete Díaz, Miguel ; Navarro Cía, Miguel ; Engheta, Nader (IOP Publishing, 2014) Artículo / Artikulua

Graded index ε near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose ...
