From: First experimental demonstration of an isotropic electromagnetic cloak with strict conformal mapping
Near-field measurement results for unidirectional cloak.
(a), (b), (c) and (d) correspond to the measuring frequencies of 4.0, 5.0, 6.0 and 7.0 GHz, respectively. The cloaking performance is degraded at higher frequencies because of the dispersions of the metamaterial inclusions used in our samples. The cyan disk represents the hiding region.
