Abstract

Based on the concept of complementary media and optical transformation, a multifunctional complementary cloak composed of homogeneous anisotropic materials with no singularities is proposed in this paper. The full-wave simulations based on the finite element method are performed to demonstrate the multifunctional characteristics of the proposed multifunctional cloak. The simulation results show that the proposed multifunctional cloak can be used as a complementary cloak, a transparency device, and an illusion cloak. In addition, the effect of loss on the performance of the multifunctional cloak is analyzed for future practical application.
