Regular and anomalous extraordinary optical transmission at the THz-gap
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
In this paper Anomalous Extraordinary Transmission (ET) is
reported for s-polarization of low loss doubly periodic subwavelength hole
arrays patterned on polypropylene (PP) substrates by conventional contact
photolithography ...
Left-handed extraordinary optical transmission through a photonic crystal of subwavelength hole arrays
(Optical Society of America, 2006)
info:eu-repo/semantics/article,
Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as photonic band-gap,
extraordinary optical transmission and left-handed propagation. Up to now,
relations of photonic ...
Extraordinary transmission and left-handed propagation in miniaturized stacks of doubly periodic subwavelength hole arrays
(Optical Society of America, 2007)
info:eu-repo/semantics/article,
Metallic plates embedded between dielectric slabs and
perforated by rectangular arrays of subwavelength holes with a dense
periodicity in one of the directions support extraordinary transmission (ET)
phenomena, viz. strong ...
Electroinductive waves role in left-handed stacked complementary split rings resonators
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
In this letter it is presented a Left-Handed Metamaterial design route
based upon stacked arrays of screens made of complementary split rings
resonators under normal incidence in the microwave regime. Computation of ...
Millimeter-wave phase resonances in compound reflection gratings with subwavelength grooves
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
Experimental evidence of phase resonances in a dual-period
reflection structure comprising three subwavelength grooves in each
period is provided in the millimeter-wave regime. We have analyzed and
measured the response ...
Polypropylene-substrate-based SRR- and CSRR-metasurfaces for submillimeter waves
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
In this paper it is presented the fabrication of low loss millimeter
wave metamaterials based on patterning on polypropylene substrates by
conventional contact photolitography. We study numerically and
experimentally ...
Planoconcave lens by negative refraction of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
This work presents the design of a planoconcave parabolic
negative index metamaterial lens operating at millimeter wavelengths
fabricated by using stacked subwavelength hole arrays. A staircase
approximation to the ideal ...
Negative refraction in a prism made of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as negative refraction
index, perfect lenses, and invisibility. However, losses are one of the big
challenges to be ...
Experimental demonstration of deeply subwavelength dielectric sensing with epsilon-near-zero (ENZ) waveguides
(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 ...
Photonic nanojets with mesoscale high-index dielectric particles
(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, ...
