The dispersion of nanoparticles in a nematic liquid crystal host medium provides an efficient way of designing tunable optical metamaterials that respond from the visible to the Terahertz and microwave regime. As studied in this article, these systems exhibit much larger birefringence than the nematic host and possess sub-unity, zero, and even negative refractive indices with unique reflection and transmission properties. These tunable optical metamaterials will enable a wide range of application possibilities in next-generation reflective, transmissive, modulation and switching elements and devices.
