# Scattering by curvatures, radiationless sources, transmission eigenfunctions and inverse scattering problems

@article{Blsten2018ScatteringBC, title={Scattering by curvatures, radiationless sources, transmission eigenfunctions and inverse scattering problems}, author={Eemeli Bl{\aa}sten and Hongyu Liu}, journal={arXiv: Analysis of PDEs}, year={2018} }

We consider several intriguingly connected topics in the theory of wave propagation: geometrical characterizations of radiationless sources, non-radiating incident waves and interior transmission eigenfunctions, and their applications to inverse scattering problems. Our major novel discovery is a certain localization and geometrization property of waves in the aforementioned scenarios.
We first show that a scatterer, which might be an active source or an inhomogeneous index of refraction… Expand
