Abstract: Tunable optical structures operating based on slot resonances can be produced with periodic structures where each period includes at least two parallel nanobars with a slot therebetween. The slots include periodic notches served to generate resonances, the wavelength and the quality-factor of which can be controlled by applying bias voltages to nanobars thus generating mechanical movement of such nanobars. Phase modulators with close to unity reflection and beam steering devices can also be made based on these concepts.

Abstract: Cascaded metasurfaces can control the phase, amplitude and polarization of an electromagnetic beam, shaping it in three dimensional configuration not achievable with other methods. Each cascaded metasurface has dielectric or metallic scatterers arranged in a period array. The shape of the scatterers determines the three dimensional configuration of the output beam and is determined with iterative calculations through computational simulations.

Abstract: A metasurface is defined by an array of scattering elements having a U shape, where the geometrical dimensions determining the U shape are determined according to the different phase profiles that the metasurface is meant to generate in response to an incident electromagnetic wave. The metasurface, therefore, generates different phase shifts as a function of the incident electromagnetic wave.
