Tunable beam steering enabled by graphene metamaterials.
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 of each graphene layer. This can arbitrarily tailor the spatial distribution of the phase of the transmitted beam, providing mechanisms for active beam steering. Three dif...
متن کاملZero loss magnetic metamaterials using powered active unit cells.
We report the design and experimental measurement of a powered active magnetic metamaterial with tunable permeability. The unit cell is based on the combination of an embedded radiofrequency amplifier and a tunable phase shifter, which together control the response of the medium. The measurements show that a negative permeability metamaterial with zero loss or even gain can be achieved through ...
متن کاملExperimental Realization of a Polarization-Independent Ultraviolet/Visible Coaxial Plasmonic Metamaterial
We report the experimental realization of an optical metamaterial composed of a hexagonal array of coaxial plasmonic metal/insulator/metal waveguides that shows strong polarization-independent optical mode index dispersion in the ultraviolet/blue. The metamaterial is composed of silicon coaxes with a well-defined diameter in the range of 150-168 nm with extremely thin sidewalls (13-15 nm), embe...
متن کاملFabrication of optical negative-index metamaterials: Recent advances and outlook
A status report on optical negative-index-metamaterial fabrication is given. The advantages, drawbacks and challenges of different fabrication techniques including electron-beam lithography (EBL), focused-ion beam (FIB) milling, interference lithography (IL) and nanoimprint lithography (NIL) and direct laser writing are outlined. Since the possibility of creating a truly three-dimensional (3D) ...
متن کاملEnhanced diffraction from a grating on the surface of a negative-index metamaterial.
We show by numerical simulation as well as by measurements on negative-index metamaterial wedge samples, that the unavoidable stepping of the refraction interface-due to the finite unit-cell size inherent to metamaterials-can give rise to a well-defined diffracted beam in addition to the negatively refracted beam. The direction of the diffracted beam is consistent with elementary diffraction th...
