Inverse scattering in an asymptotically flat multilayer domain

Michel Cristofol, Yves Dermenjian, Hiroshi Isozaki +1

We consider a scattering problem for a wave equation $\partial_{t}^{2} u = \frac{1}{g} \partial_{i} (g g^{ij} \partial_{j}) u$ in a multilayer domain $Î©\subset {\bf R}^{n+1}_x =…

Concentration and non-concentration of eigenfunctions of second-order elliptic operators with a divergence form in layered media

Matania Ben-Artzi, Yves Dermenjian

Let $I^c ◯$ ' $\subset$ R^d , d = 1, 2, . . . be an open bounded smooth domain, and $I^c ◯ = I^c ◯^{'} \times (0, H) \subset R^{d} \times R_{+} .$ The coordinates in $I^c ◯$ are designat…
