Wave scattering by metal-dielectric multilayer structures with gain

Savelev, R. S.; Shadrivov, I. V.; Kivshar, Yuri


We study wave scattering by multilayer metal-dielectric structures of a finite extent characterized by a hyperbolic-like dispersion. We find the regimes of wave propagation when substantial compensation of losses becomes possible with the use of a gain medium with realistic parameters. We discuss the Purcell effect in these structures and its possible implications on the performance of the loss compensation.
