dc.description
In my talk I will present two recent works focused on the perfect absorption and transmission of waves through interferometric cancellation of backscattering. In the rst case [1,2], we demonstrate that even a weakly absorbing lm can be turned into a coherent perfect absorber by building a degenerate cavity around it. This special cavity perfectly couples incoming light elds with arbitrary wavefronts into the absorber even for the case that light is a dynamically varying speckle pattern. In the second case [3], we demonstrate how to construct an anti-re ection structure for a complex scattering system like a disordered medium. Similar to an anti-re ection coating for conventional eye-glasses, this structure leads to perfect transmission across the scattering system by suppressing back-scattering for any incoming wavefront. If time permits, I will also say a few words about the topological origin of the above e ects and how this aspect can be used to engineer thermal radiation [4].
