Paper Abstract

We discuss the concept of infrared cloaking using nanosphere dispersed liquid crystal (NDLC) matematerial in cylindrical geometry for TM polarization. The system consists of layers of NDLC with different values of ordinary refractive index and the same value of extraordinary refractive index of liquid crystal host. Finite element calculations (COMSOL Multiphysics), which include the Poynting vector calculations, show that scattering from the hidden object is limited in the presence of the layered cloak.
