Wideband backscattering reduction at terahertz using compound reflection grating
(Optical Society of America, 2017) Artículo / Artikulua,
Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ...
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 ...
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 ...
