Abstract:
A recently published theory has suggested that a cloak of invisibility is in principle possible, at least
over a narrow frequency band. We describe here the first practical realization of such a cloak; in
our demonstration, a copper cylinder was “hidden” inside a cloak constructed according to the
previous theoretical prescription. The cloak was constructed with the use of artificially structured
metamaterials, designed for operation over a band of microwave frequencies. The cloak decreased
scattering from the hidden object while at the same time reducing its shadow, so that the cloak
and object combined began to resemble empty space.
