Wide-spectrum optical hyperbolic metamaterial based on reverse hexagonal lyotropic liquid crystal.

Abstract: Reverse hexagonal lyotropic liquid crystal template is proposed to achieve optical hyperbolic metamaterial composed of silver nanowire arrays. All angle negative refraction is obtained during the wide wavelength range from near-infrared to visible light. Hyperbolic metamaterial incorporated with gain dye molecules is calculated to show the possibility of eliminating energy losses and the transmittance can be enhanced in the selected wavelength range.
