Far-field and near-field physics of extraordinary THz transmitting hole-array antennas
(IEEE, 2019)
Artículo / Artikulua,
Despite three decades of effort, predicting accurately
extraordinary transmission through subwavelength hole
arrays has proven challenging. The lack of quantitative design
and modeling capability to take into account ...
Angle-susceptible sensing metasurface in terahertz regime
(EDP Sciences, 2018)
info:eu-repo/semantics/conferenceObject,
Nowadays thin-film coatings and structures are widely used in advanced industrial and scientific ap-plications that makes the tasks of thin-film sensing highly demanded in practice. Last decade, stimulated by progress in ...
Experimental demonstration of a millimeter-wave metallic ENZ lens based on the energy squeezing principle
(IEEE, 2015)
info:eu-repo/semantics/article,
The performance of an epsilon-near zero (ENZ) plano-concave lens is experimentally demonstrated and verified at the D-band of the millimeter-waves. The lens is comprised of an array of narrow metallic waveguides near cut-off ...
Terahertz carpet cloak based on a ring resonator metasurface
(American Physical Society, 2015)
info:eu-repo/semantics/article,
In this work we present the concept and design of an ultrathin (λ/22) terahertz (THz) unidirectional carpet cloak based on the local phase compensation approach enabled by gradient metasurfaces. A triangular surface bump ...
Comprehensive analysis of photonic nanojets in 3D dielectric cuboids excited by surface plasmons
(Wiley, 2016)
info:eu-repo/semantics/article,
In this paper we study the excitation of photonic nanojets (PNJ) in 3D dielectric cuboids by surface plasmons at telecommunication wavelengths. The analysis is done using the effective refractive index approach. It is shown ...
Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries
(MDPI, 2019)
Artículo / Artikulua,
The use of metasurfaces operating in the terahertz regime as biosensor devices has attracted increased interest in recent years due to their enhanced sensitivity and more accurate detection capability. Typical designs are ...
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 ...
