Abstract
The superscattering of a partially coherent beam by a multilayer cylinder is investigated. It is found that multiple resonances with different total angular momenta have almost the same frequency for an arbitrary degree of coherence of the incident field. However, the angular distribution of the superscattering field is intensively affected by the partially coherent light. A large “shadow” in the forward direction caused by the superscattering can change to the horizontal direction by tuning the spatial coherence of the incident field. This provides a new way to steer the superscattering field by changing the degree of coherence of the incident field.
