Experimental demonstration of deeply subwavelength dielectric sensing with epsilon-near-zero (ENZ) waveguides
Beruete Díaz, Miguel
; Engheta, Nader; Pacheco-Peña, Víctor (American Institute of Physics, 2022)
Artículo / Artikulua 
In this Letter, an all metallic sensor based on ε-near-zero (ENZ) metamaterials is studied both numerically and experimentally when working at microwave frequencies. To emulate an ENZ medium, a sensor is made by using a ... -
On the performance of an ENZ-based sensor using transmission line theory and effective medium approach
Pacheco-Peña, Víctor ; Beruete Díaz, Miguel ; Rodríguez Ulibarri, Pablo ; Engheta, Nader (IOP Publishing, 2019)
Artículo / Artikulua
In this paper we perform an in-depth theoretical studyofa sensing platform based on epsilon-near- zero (ENZ) metamaterials. The structure proposed for sensing is a narrow metallic waveguide channel. An equivalent circuit ... -
Photonic nanojets with mesoscale high-index dielectric particles
Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (AIP Publishing, 2019)
Artículo / Artikulua
In this work, we demonstrate the ability of high-index dielectric particles immersed in air to generate photonic nanojets with extreme resolution (∼0.06λ0). Both 2D (cylindrical) and 3D (spherical) particles are analyzed, ... -
Quantum antireflection temporal coatings: quantum state frequency shifting and inhibited thermal noise amplification
Liberal Olleta, Íñigo ; Vázquez Lozano, Juan Enrique; Pacheco-Peña, Víctor (wiley, 2023)
Artículo / Artikulua
The quantum optical response of antireflection temporal coatings (ATCs), that is, matching temporal layers that suppress the generation of backward waves in temporal boundaries, is investigated. The results reveal that ... -
Steering surface plasmons with a graded index dielectric medium
Beruete Díaz, Miguel ; Pacheco-Peña, Víctor (IOP Publishing, 2018)
Artículo / Artikulua
The arbitrary control of surface plasmon (SP) propagation has become an intense research topic for several decades. This is due to the fact that they can be used in a variety of fields such as optical trapping, nanoantennas ... -
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
Jáuregui López, Irati ; Orazbayev, Bakhtiyar ; Pacheco-Peña, Víctor ; Beruete Díaz, Miguel (MDPI, 2020)
Artículo / Artikulua
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
