Abstract

Based on coordinate transformation, a carpet cloak made from nonmagnectic dielectric cylinders is designed, simulated and tested experimentally in this paper. By manipulating the periodicity of the dielectric cylinders, it is possible to achieve the required dielectric map and therefor the propagate direction of the electromagnetic waves. The scattering reduction effects of the cloak are verified through both simulation and experiment from 7 GHz to 9 GHz with the incidence of an open-end waveguide. The proposed all-dielectric cloak is broad band, low loss and easy to fabricate.
