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 ...
Evanescently fed electromagnetic band-gap horn antennas and arrays
(IEEE, 2012)
Artículo / Artikulua,
The design of a horn antenna based on electromagnetic band-gap structures (EBGs) and fed by evanescent fields in the containing periodic structure is presented. Such all-dielectric antennas can form compact arrays and ...
The Canfranc Axion Detection Experiment (CADEx): search for axions at 90 GHz with Kinetic Inductance Detectors
(IOP Publishing, 2022)
Artículo / Artikulua,
We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to probe dark matter axions with masses in the range 330–460 μeV, within the W-band (80–110 GHz), an unexplored parameter space in the ...
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
(IEEE, 2018)
Artículo / Artikulua,
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
Photonic-assisted 2-D terahertz beam steering enabled by a LWA array monolithically integrated with a BFN
(Optica, 2022)
Artículo / Artikulua,
A novel photonic-assisted 2-D Terahertz beam steering chip using only two tuning
elements is presented. The chip is based on an array of three leaky wave antennas (LWAs) with
a monolithically integrated beamforming network ...
Reduced loss and prevention of substrate modes with a novel Coplanar Waveguide based on Gap Waveguide technology
(MDPI, 2023)
Artículo / Artikulua,
The Gap Waveguide technology utilizes an Artificial Magnetic Conductor (AMC) to prevent the propagation of electromagnetic (EM) waves under certain conditions, resulting in various gap waveguide configurations. In this ...
New coplanar waveguide based on the gap waveguide technology
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
A new planar waveguide, coined Inverted coplanar gap waveguide is presented. The concept of gap waveguides and parallel plate suppression between perfect magnetic and a perfect electric conductors is applied to coplanar ...
3-D printed horn antennas and components performance for space and telecommunications
(IEEE, 2018)
Artículo / Artikulua,
In this work, a study of the performance of several
antennas and components, manufactured using an accurate
stereolithography 3D printer and resin for maximum accuracy
and detail, is carried out. Electroless plating of ...
Ultrathin and high-efficiency Pancharatnam-Berry phase metalens for millimeter waves
(AIP Publishing, 2021)
Artículo / Artikulua,
Applying the Pancharatnam–Berry (PB) principle to half-wave plate (HWP) metasurfaces allows the manipulation of wavefronts along with the conversion of the handedness of circularly polarized incident waves by simply rotating ...
Real-time imaging with frequency scanning array antenna for industrial inspection applications at W band
(Springer, 2018)
info:eu-repo/semantics/article,
A real-time imaging system based on a frequency scanning antenna for conveyor belt setups is presented in this paper. The frequency scanning antenna together with an inexpensive parabolic reflector operates at the W band ...
