Zoned fishnet lens antenna with reference phase for side lobe reduction
Pacheco Peña, Víctor
; Navarro Cía, Miguel ; Orazbayev, Bakhtiyar ; Minin, Igor V.; Minin, Oleg V.; Beruete Díaz, Miguel (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 ... -
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. ... -
Zuntz optikoan oinarritutako sentsoreen prestazioen muga-efektu berria, egituren egoera monitorizatzea helburu
Iribas Pardo, Haritz; Mariñelarena Ollacarizqueta, Jon; Loayssa Lara, Alayn (Udako Euskal Unibertsitatea, 2017)
Contribución a congreso / Biltzarrerako ekarpena
Brillouin denbora-eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak estruktura handien (120 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna dute, metro bateko bereizmen espazialarekin. ... -
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 ...
