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 ...
Doubling the propagation distance of surface plasmon polaritons
(SPIE, 2016)
Artículo / Artikulua,
A novel passive repeater, based on a chain of 3D dielectric particles, has

Wide angle terahertz sensing with a cross-dipole frequency selective surface
(AIP Publishing, 2016)
Artículo / Artikulua,
In this work, a terahertz sensor based on a cross dipole frequency selective surface is analyzed and experimentally tested. The sensing structure is optimized for operation at the fundamental band- stop resonance near ...
Indium tin oxide refractometer in the visible and near infrared via lossy mode and surface plasmon resonances with Kretschmann configuration
(AIP Publishing, 2016)
Artículo / Artikulua,
An indium tin oxide (ITO) refractometer based on the generation of lossy mode resonances (LMRs) and surface plasmon resonances (SPRs) is presented. Both LMRs and SPRs are excited, in a single setup, under grazing angle ...
Accurate circuit modeling of fishnet structures for negative-index-medium applications
(IEEE, 2016)
Artículo / Artikulua,
Metallic plates with a two-dimensional (2D) periodic distribution of sub-wavelength apertures are known to exhibit extraordinary transmission of electromagnetic waves. Stacking two or more of such plates gives place to the ...
Epsilon-near-zero metalenses operating in the visible
(Elsevier, 2016)
Artículo / Artikulua,
Several converging lenses working in the permittivity near to zero (ENZ) regime at optical frequencies are designed using an array of metal-dielectric-metal plasmonic waveguides. These plasmonic waveguides show a dispersive ...
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 ...
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 ...
Tunable beam steering enabled by graphene metamaterials
(Optical Society of America, 2016)
Artículo / Artikulua,
We demonstrate tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. The effective refractive index of such metamaterials can be manipulated by changing the chemical potential ...
Broadband frequency and angular response of a sinusoidal bull’s eye antenna
(IOP Publishing, 2016)
Artículo / Artikulua,
A thorough experimental study of the frequency and beaming angle response of a metallic
leaky-wave bull’s eye antenna working at 77 GHz with a sinusoidally corrugated profile
is presented. The beam scanning property of ...
