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 ...
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
been proposed and numerically simulated.
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 ...
Terajets produced by dielectric cuboids
(AIP Publishing, 2014)
Artículo / Artikulua,
The capability of generating terajets using three-dimensional (3D) dielectric cuboids working at terahertz (THZ) frequencies (as analogues of nanojets in the infrared band) is introduced and studied numerically. The focusing ...
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 ...
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 ...
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 ...
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 ...
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 ...
