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 ...
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 ...
