Annular apertures in metallic screens as extraordinary transmission and frequency selective surface structures
(IEEE, 2017)
Artículo / Artikulua,
A 2-D periodic array of annular apertures (or ring slots) is studied using an accurate circuit model. The model accounts for distributed and dynamic effects associated with the excitation of high-order modes operating above ...
Planar holographic metasurfaces for terahertz focusing
(Springer Nature, 2015)
info:eu-repo/semantics/article,
Scientists and laymen alike have always been fascinated by the ability of lenses and mirrors to control light.
Now, with the advent of metamaterials and their two-dimensional counterpart metasurfaces, such
components can ...
Polarized left-handed extraordinary optical transmission of subterahertz waves
(Optical Society of America, 2007)
info:eu-repo/semantics/article,
In this paper we design and measure a metamaterial polarizing
device working in the sub-terahertz range. The polarizer is based on a
modified version of our previous miniaturized Stacked Hole Array (SHA)
structure, an ...
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 ...
Broadband spoof plasmons and subwavelength electromagnetic energy confinement on ultrathin metafilms
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
A complementary split ring resonator (CSRR)-based metallic
layer is proposed as a route to mimic surface plasmon polaritons. A
numerical analysis of the textured surface is carried out and compared to
previous prominent ...
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 ...
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 ...
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 ...
