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 ...
Wideband backscattering reduction at terahertz using compound reflection grating
(Optical Society of America, 2017)
Artículo / Artikulua,
Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ...
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 ...
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
(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 ...
One-way quasiplanar terahertz absorbers using nonstructured polar dielectric layers
(American Physical Society, 2017)
Artículo / Artikulua,
A concept of quasiplanar one-way transparent terahertz absorbers made of linear isotropic materials is presented. The resulting structure consists of a homogeneous absorbing layer of polar dielectric, GaAs, a dispersion-free ...
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 ...
3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
(IEEE, 2017)
Artículo / Artikulua,
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ...
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 ...
Mid-infrared spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
(Springer, 2017)
Artículo / Artikulua,
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were ...
