All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
Orazbayev, Bakhtiyar
; Torres Landívar, Víctor ; Pacheco-Peña, Víctor ; Falcone Lanas, Francisco Javier ; Teniente Vallinas, Jorge ; Beruete Díaz, Miguel ; Sorolla Ayza, Mario ; Navarro Cía, Miguel ; Engheta, Nader (IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena 
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ... -
Controlling the direction of propagation of surface plasmons via graded index effective dielectric media
Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (IEEE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
In this work, we propose a mechanism to steer and tailor surface plasmon propagation by using graded index concepts. In this approach, a block of dielectric with fixed thickness is placed on top of a semi-infinite metal. ... -
Overcoming the diffraction limit with high-index dielectric particles
Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (IEEE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
In this communication, we propose and demonstrate the ability to produce photonic nanojets using high refractive index dielectric particles immersed in air. An extremely narrow focus is produced just at the output surface ... -
THz tripod metasurfaces for sensing applications: from the basic, to more elaborated designs
Jáuregui López, Irati ; Orazbayev, Bakhtiyar ; Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (IEEE, 2021)
Contribución a congreso / Biltzarrerako ekarpena
In this work, we propose, design, and evaluate three types of : three types of metasurfaces using tripod-shaped unit cells when working as thin-film sensing devices. The three meta-atoms of the proposed metasensors area ...
