Interaction of light with light on a nanoscale absorber. Two coherent counter-propagating beams A and B are incident on an absorber of sub-wavelength thickness, for instance, a lossy plasmonic metamaterial film. Two limiting regimes of interaction exist wherein the beams at the film interfere either (a) destructively or (b) constructively to effect total transmission or total absorption, respectively.
