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 ...
Diffusive-light invisibility cloak for transient illumination
(American Physical Society, 2016)
Artículo / Artikulua,
Invisibility in a diffusive-light-scattering medium has been recently demonstrated by employing a scattering-cancellation core-shell cloak. Unlike nondiffusive cloaks, such a device can be simultaneously macroscopic, ...
Experimental demonstration of metasurface-based ultrathin carpet cloaks for millimetre waves
(Wiley, 2016)
Artículo / Artikulua,
A metasurface carpet cloak for millimeter-wave range with polarization-independent performance is experimentally demonstrated. It is shown that the cloak is able to mimic the ground plane by fully restoring the amplitude ...
Metasurface-based ultrathin carpet cloaks for millimeter waves
(2017)
Artículo / Artikulua,
A metasurface carpet cloak for millimetre-wave range with polarization independent
performance is experimentally demonstrated. It is shown that the cloak is able to mimic the
ground plane by fully restoring the amplitude ...
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 ...
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 ...
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
(MDPI, 2020)
Artículo / Artikulua,
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
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 ...
