Abstract

Metamaterials with tunable properties are of great importance due to potential applications in super-resolution lensing and sensors. In this paper we study the feasibility of the fabrication of a metamaterial using binary nanoparticle-dispersed liquid crystal cell (NDLCC). Depending on the angle between the director axis of the LCC and the incident beam, types, radii, and volume filling fractions of the nanoparticles, a negative index of refraction cell is obtained in a certain range of frequencies. The effective index of refraction is calculated using the effective medium theory. The scattering, extinction, and absorption of such a NDLCC cell is also found. Finally, the influence of the various parameters to obtain such a negative index metamaterial has been investigated.
