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 ...
