Scattering by curvatures, radiationless sources, transmission eigenfunctions and inverse scattering problems
Emilia Blåsten, Hongyu Liu
We consider several intriguingly connected topics in the theory of wave propagation: geometrical characterizations of radiationless sources, non-radiating incident waves, interior…

Radiating and non-radiating sources in elasticity
Eemeli Blåsten, Yi-Hsuan Lin
In this work, we study the inverse source problem of a fixed frequency for the Navier's equation. We investigate that nonradiating external forces. If the support of such a force h…

Nonradiating sources and transmission eigenfunctions vanish at corners and edges
Eemeli Blåsten
We consider the inverse source problem of a fixed wavenumber: study properties of an acoustic source based on a single far- or near-field measurement. We show that nonradiating sou…
