title: Hamiltonian-based ray-tracing method with triangular-mesh representation for a large-scale cloaking device with an arbitrary shape.
abstract: Hamiltonian-based ray-tracing technique with mesh representation is presented for designing large-scale cloaking devices with three-dimensional arbitrary shapes, which have inhomogeneity and anisotropy in their electric permittivity and magnetic permeability. In order to deal with arbitrary shapes, the surfaces of the cloaking devices are represented by triangular meshes. Comparison between the result of cloaking simulations with the mesh representation and those with the rigorous function representation is presented. The numerical results showed that fine-mesh resolution is required for accurate evaluation of cloaking performances.
