Increasing surface plasmons propagation via photonic nanojets with periodically spaced 3D dielectric cuboids
(MDPI, 2016)
Artículo / Artikulua,
A structure based on periodically arranged 3D dielectric cuboids connected by photonic nanojets (PNJs) is proposed with the aim of increasing the propagation distance of surface plasmon polaritons (SPPs) at the telecom ...
Description of bow-tie nanoantennas excited by localized emitters using conformal transformation
(American Chemical Society, 2016)
Artículo / Artikulua,
The unprecedented advance experienced by nano- fabrication techniques and plasmonics research over the past few years has made possible the realization of nanophotonic systems entering into the so-called strong coupling ...
Response of complementary split ring resonators in composite stratified substrate integrated waveguide
(American Institute of Physics, 2017)
Artículo / Artikulua,
In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the
quasi-static resonance regime and embedded in a composite stratified Substrate Integrated
Waveguide (SIW) with two different ...
On the performance of the zoned fishnet metamaterial lens with positive and negative reference phase
(IEEE, 2016)
Artículo / Artikulua,
In this letter, several converging fishnet metalenses are designed using both the zoning and reference phase techniques. They are engineered with a focal length of 1.5λ0 at the design frequency of 55 GHz (λ0 = 5.45 mm) at ...
Nonbianisotropic complementary split ring resonators as angular selective metasurfaces
(Optical Society of America, 2017)
Artículo / Artikulua,
In this work, a metasurface with unconventional angular performance and composed by a nonbianisotropic complementary split ring resonator (NB-CSRR) is analyzed numerically and experimentally. A numerical study comparing ...
High aperture efficiency wide corrugations bull’s-eye antenna working at 60 GHz
(IEEE, 2017)
Artículo / Artikulua,
A full metallic Bull’s-Eye (BE) antenna operating at 60 GHz is numerically and experimentally analyzed. The antenna presents wide grooves, rather than narrow ones, which support higher order resonances that lead to a large ...
Metasurface-based ultrathin carpet cloaks for millimeter waves
(2017)
Artículo / Artikulua,
A metasurface carpet cloak for millimetre-wave range with polarization independent
performance is experimentally demonstrated. It is shown that the cloak is able to mimic the
ground plane by fully restoring the amplitude ...
Extraordinary THz transmission with a small beam spot: the leaky wave mechanism
(Wiley, 2018)
Artículo / Artikulua,
The discovery of extraordinary optical transmission (EOT) through patterned
metallic foils in the late 1990s was decisive for the development of plasmonics
and cleared the path to employ small apertures for a variety of ...
Ku band low profile asymmetric Bull’s-Eye antenna with reduced side lobes and monopole feeding
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a linearly polarized low profile and asymmetric Bull’s-Eye leaky wave antenna fed by a monopole operating at 13 GHz is presented. Broadside radiation from the monopole is achieved by surrounding it with an ...
Phase reversal technique applied to fishnet metalenses
(Hindawi, 2018)
Artículo / Artikulua,
In this work, the fishnet metamaterial is applied to several converging metalenses by combining the zoning, reference phase, and phase reversal techniques. First, the zoning and reference phase techniques are implemented ...
