Abstract

A Hamiltonian-based ray tracing technique is applied to the evaluation of the performance of cloaking devices with arbitrary shapes based on full-mesh representation. The constitutive parameters of cloaking devices are calculated by the finite element method. The cloaking characteristics of a double cylindrical cloaking device and a huge cloaking device with a completely arbitrary shape are evaluated. The numerical results showed that fine mesh structure is required for better cloaking performance. The full-mesh representation is useful for fabrication design.
