Abstract
A common type of inverse scattering problems involves detecting information about an unknown inhomogeneity by sending incident waves and measuring scattered waves in the far-field. However, in some cases, a phenomenon called non-scattering can occur, where no scattered waves can be observed from the exterior of the inhomogeneity when probed by an incident wave. This corresponds to a nontrivial kernel of the far-field operator. In this talk, I will present recent work on the necessary conditions for the existence of non-scattering waves for certain inhomogeneities.
Series This talk is part of the Isaac Newton Institute Seminar Series series.
