Observation of reflectionless absorption due to spatial Kramers–Kronig profile

Observation of reflectionless absorption due to spatial Kramers–Kronig profile

Reflectionless absorption independent of the angle of incidence usually requires the introduction of gain media into the system. Here, Ye et al. implement a recent theoretical proposal to achieve this with a spatially varying permittivity, showing that this approach is experimentally feasible.
