Wood zone plate fishnet metalens
(EDP Sciences, 2015)
Artículo / Artikulua,
Fresnel-zone plate lenses provide focusing performance while having low profile. Unfortunately, they usually display higher reflection losses than conventional dielectric lenses. Here, we demonstrate a low-profile Wood ...
Zoned fishnet lens antenna with reference phase for side lobe reduction
(IEEE, 2015)
Artículo / Artikulua,
Reduction of first side lobe level and nulls in artificial fishnet metalenses is accomplished here by applying the reference phase concept along with the zoning technique. Higher focusing efficiency is achieved for a ...
Localized photonic jets from flat, three-dimensional dielectric cuboids in reflection mode
(Optical Society of America, 2015)
Artículo / Artikulua,
A photonic jet (a terajet at terahertz frequencies) commonly denotes a specific, spatially localized region in the near field on the front side of a dielectric particle with a diameter comparable with the wavelength ...
Multifrequency focusing and wide angular scanning of terajets
(Optical Society of America, 2015)
Artículo / Artikulua,
In the past, it has been demonstrated that it is possible to produce terajets with high resolution at its focus using 3D dielectric cuboids under plane-wave illumination. Here, a systematic study of the harmonic and angular ...
Focus on terahertz plasmonics
(IOP Publishing, 2015)
info:eu-repo/semantics/article,
Plasmonics is one of the growing fields in modern photonics that has garnered increasing interest over
the last few years. In this focus issue, the specific challenges concerning terahertz plasmonics have
been addressed ...
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 ...
Soret fishnet metalens antenna
(Springer Nature, 2015)
info:eu-repo/semantics/article,
At the expense of frequency narrowing, binary amplitude-only diffractive optical elements emulate refractive
lenses without the need of large profiles. Unfortunately, they also present larger Fresnel reflection loss ...
Experimental demonstration of lossy mode and surface plasmon resonance generation with Kretschmann configuration
(Optical Society of America, 2015)
Artículo / Artikulua,
Lossy mode resonances (LMRs) and surface plasmon resonaces
(SPRs) are obtained experimentally with a Kretschmann
configuration using a BK7 glass prism with all sides polished
and coated with indium tin oxide (ITO). The ...
All-dielectric periodic terajet waveguide using an array of coupled cuboids
(AIP Publishing, 2015)
Artículo / Artikulua,
In this paper, the recently proposed technique to produce photonic jets (terajets at terahertz (THz) frequencies) using 3D dielectric cuboids is applied in the design of a mesoscale cuboid-chain wave- guide. The chains are ...
Multiband one-way polarization conversion in complementary split-ring resonator based structures by combining chirality and tunneling
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
Multiband one-way polarization conversion and strong
asymmetry in transmission inspired by it are demonstrated in ultrathin
sandwiched structures that comprise two twisted aperture-type arrays of
complementary split-ring ...
