On scattering behavior of corner domains with anisotropic inhomogeneities: part II
Pu-Zhao Kow, Mikko Salo, Henrik Shahgholian
We study the scattering behavior of an anisotropic inhomogeneous Lipschitz medium at a fixed wave number, continuing our previous work [SIAM J. Math. Anal., 56(4):4834-4853, 2024]…

A free boundary approach to non-scattering obstacles with vanishing contrast
Mikko Salo, Henrik Shahgholian
Motivated by questions in inverse scattering theory, we develop free boundary methods in obstacle problems where both the solution and the right hand side of the equation may have…

Increasing resolution and instability for linear inverse scattering problems
Pu-Zhao Kow, Mikko Salo, Sen Zou
In this work we study the increasing resolution of linear inverse scattering problems at a large fixed frequency. We consider the problem of recovering the density of a Herglotz wa…
