Abstract:
A method for fabricating a hyperbolic metamaterial coating having a near-zero refractive index is disclosed. The direction of propagating light changes by means of generating subwavelength structures that alter the coatings permittivity and permeability. The coating can be deposited on lenses or incorporated into optical devices. This type of metamaterial can be utilized to direct light towards sensors or to collect light efficiently.
