Terahertz active spatial filtering through optically tunable hyperbolic metamaterials
Carlo Rizza, Alessandro Ciattoni, Elisa Spinozzi +1
We theoretically consider infrared-driven hyperbolic metamaterials able to spatially filtering terahertz radiation. The metamaterial is a slab made of alternating semiconductor and…

Restoring of optical resonances in subwavelength hyperbolic etalons
Alessandro Ciattoni, Elisa Spinozzi
We give a solution to the fundamental problem of restoring optical resonances in deep subwavelength structures by resorting to indefinite metamaterials. We prove that a nanometric…

Ultrathin optical switch based on a liquid crystal/silver nanoparticles mixture as a tunable indefinite medium
Elisa Spinozzi, Alessandro Ciattoni
We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts…
