On Cloaking Effect in Nanosphere Dispersed Liquid Crystal Metamaterial
Grzegorz Pawlik, Wiktor Walasik, Michal Jarema, Antoni C. Mitus and Iam Choon Khoo
Nanosphere dispersed liquid crystal metamaterial is a tunable system for which external electrostatic field, anchoring forces or temperature influence strongly the character of an inhomogeneous spatial distribution of an effective refractive index. Those features make this system a promising candidate for a design of a controlled molding of light flow and, in particular, for a design of an invisibility cloak.We review briefly recent results related to a potential cloak applications on the basis of this system and discuss further extensions of the model.
