Claim Text:
1. A metafilm for loss-induced super-scattering of a photon at a wavelength, comprising: an electrically conductive substrate having a planar surface, a sub-wavelength thickness and a first complex permittivity; and a plurality of dimers disposed in a planar array on said planar surface of said substrate, each dimer having a sub-wavelength period and including loss and gain elements separated by a sub-wavelength distance, each element having a sub-wavelength span and a sub-wavelength width along said planar array, said loss element having a second complex permittivity, said gain element having a third complex permittivity, wherein said first, second and third complex permittivities respectively include first, second and third real components, and respectively include first, second and third imaginary components, said second and third real components are equal, said second imaginary component is higher than said third imaginary component, and the metafilm emits the photon in response to increasing one of said first imaginary component and said second imaginary component.
