System, method and apparatus for cloaking

A method of cloaking an object, the method comprising:

• providing a structure formed of a metamaterial;
• and
• disposing the object to be cloaked such that the structure is positioned between the object and an observer,
• wherein the metamaterial has a permittivity less than unity and a permittivity approximately equal to unity.

A method of designing a cloaking structure, the method comprising:

• selecting a dielectric material;
• selecting a filler material having a permittivity less than zero;
• and
• adjusting at least one of a distribution, a quantity or a dimension of the filler material within the dielectric material such that, at a design wavelength, a permittivity of a composite material comprised of the dielectric material and the filler material varies with a distance such that a visibility of an object disposed within the cloaking structure is reduced, and the region behind the object is visible.

A cloaked object, the object comprising:

• an object having a electromagnetic scattering property;
• and
• a structure disposable between the object and an observer,
• wherein the structure further comprises:
• a material having a permeability approximately equal to unity and a permittivity between approximately unity and approximately zero.
