Metafilm for loss-induced super-scattering and gain-induced absorption of electromagnetic wave

Patent image
NSWCDD

A metafilm is provided for operating on a photon at a defined wavelength, for super-scattering, absorption, and for laser absorber switch. The metafilm includes dimers and a conductive substrate for embedding the dimers in an array. Each dimer comprises a pair of a gain element and a loss element. The substrate, and the gain and loss elements have complex permittivity values. The metafilm super-scatters (e.g., lases) the photon in response to increasing the imaginary component of either the substrate or the loss element, and absorbs the photon in response to increasing the imaginary component of the gain element.
