Construction of artificial point sources for a linear wave equation in unknown medium
Anna Kirpichnikova, Jussi Korpela, Matti Lassas +1
We study the wave equation on a bounded domain of and on a compact Riemannian manifold with boundary. We assume that the coefficients of the wave equation are unk…

Focusing waves in unknown media by modified time reversal iteration
Matias Dahl, Anna Kirpichnikova, Matti Lassas
We study the wave equation in a bounded domain or on a compact Riemannian manifold with boundary. Assume that we are given the hyperbolic Neumann-to-Dirichlet map on the boundary c…
