Direct observation of ideal electromagnetic fluids
Li, Hao; Zhou, Ziheng; Sun, Wangyu; Lobet, Michaël; Engheta, Nader; Liberal Olleta, Íñigo
; Li, Yue (Springer Nature, 2022)
Artículo / Artikulua 
Near-zero-index (NZI) media have been theoretically identified as media where electromagnetic radiations behave like ideal electromagnetic fluids. Within NZI media, the electromagnetic power flow obeys equations similar ... -
Effect of epsilon-near-zero modes on the casimir interaction between ultrathin films
Gong, Tao; Liberal Olleta, Íñigo ; Spreng, Benjamin; Camacho, Miguel; Engheta, Nader; Munday, Jeremy N. (American Physical Society, 2023)
Artículo / Artikulua
Vacuum fluctuation-induced interactions between macroscopic metallic objects result in an attractive force between them, a phenomenon known as the Casimir effect. This force is the result of both plasmonic and photonic ... -
Electrically switchable Casimir forces using transparent conductive oxides
Gong, Tao; Spreng, Benjamin; Camacho, Miguel; Liberal Olleta, Íñigo ; Engheta, Nader; Munday, Jeremy N. (American Physical Society, 2022)
Artículo / Artikulua
Casimir forces between charge-neutral bodies originate from quantum vacuum fluctuations of electromagnetic fields, which exhibit a critical dependence on material's electromagnetic properties. Over the years, in situ ... -
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 ... -
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
Pacheco-Peña, Víctor ; Engheta, Nader; Kuznetsov, Sergei A.; Gentselev, Alexandr; Beruete Díaz, Miguel (American Physical Society, 2017)
Artículo / Artikulua
The terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ... -
Near-zero-index media as electromagnetic ideal fluids
Liberal Olleta, Íñigo ; Lobet, Michaël; Li, Yue; Engheta, Nader (National Academy of Sciences, 2020)
Artículo / Artikulua
Near-zero-index (NZI) supercoupling, the transmission of electromagnetic waves inside a waveguide irrespective of its shape, is a counterintuitive wave effect that finds applications in optical interconnects and engineering ... -
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 ...
