No extreme material parameters needed
Abstract
An approach to hiding objects levitating or flying above a conducting sheet is suggested in this letter. The proposed device makes use of isotropic negative-refractive-index materials without extreme material parameters, and creates an illusion of a remote conducting sheet. Numerical simulations are performed to investigate the performance of this cloak in two-dimensional (2D) and three-dimensional (3D) cases.
