On the growth properties of interior transmission eigenfunctions near corners
Emilia L. K. Blåsten, Valter Pohjola
We investigate the localization and vanishing of interior transmission eigenfunctions at corners. Past numerical computations suggest that these eigenfunctions localize at no…
Inverse Problems for Screens
Emilia Blåsten, Petri Ola, Lassi Päivärinta
We study the inverse scattering from a screen with using only one incoming time--harmonic plane wave but with measurements of the scattered wave done at all directions. Especially…
Inverse problems for locally perturbed lattices -- Discrete Hamiltonian and quantum graph
Emilia Blåsten, Pavel Exner, Hiroshi Isozaki +2
We consider the inverse scattering problems for two types of Schrödinger operators on locally perturbed periodic lattices. For the discrete Hamiltonian, the knowledge of the S-matr…
Unique determination of the shape of a scattering screen from a passive measurement
Emilia Blåsten, Lassi Päivärinta, Sadia Sadique
We consider the problem of fixed frequency acoustic scattering from a sound-soft flat screen. More precisely the obstacle is restricted to a two-dimensional plane and interacting w…
On an electromagnetic problem in a corner and its applications
Emilia Blåsten, Hongyu Liu, Jingni Xiao
Let be a (non-degenerate) truncated corner in with being its apex, and $\mathbf{F}_j\in C^α(\overline{\mathcal{K}^{r_0…
