Abstract


Taking advantage of a simple linear coordinate transformation we design a carpet cloak with homogeneous anisotropic medium and then practically realize the device with multilayer of alternating normal dielectric slabs based on the effective medium theory. Experimental tests have demonstrated pronounced cloaking effect in a very broad band from 8 GHz to 18 GHz due to the low loss, non-dispersive feature of the multilayer dielectric structure.
