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.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The requirement of matched electric and magnetic responses and additional tilted anisotropy terms in both tensors can be relaxed by using a reduced parameter approximation, leaving only tilted anisotropy from a biaxial permittivity tensor.

    “The requirement of responses in matched values and the additional tilted anisotropy terms in both tensors are relaxed in two steps.”

  • The reduced parameter approximation technique is valid when impedance mismatch is negligible or when the material profile is slowly varying in the scale of wavelength.

    “The so-called reduced parameter approximation technique is often employed for metamaterials requiring both electric and magnetic responses [25], which is valid when impedance mismatch is negligible or when the material profile is slowly varying in the scale of wavelength.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
