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 =…

Rellich type theorem and unique continuation property for discrete Maxwell operators

Hiroshi Isozaki, Olivier Poisson

We study the Rellich type theorem (RT) for the Maxwell operator __ D = D____0 on Z3 in a constant anisotropic medium, i.e., the permittivity and permeability of which are constant…

Inverse problem for the discrete Maxwell equations in a bounded paving

Olivier Poisson

We consider the discrete anisotropic Maxwell operator DaH0 on a bounded paving $I^c ◯$ $\subset$ Z3 , where H0 denotes discrete isotropic Maxwell operator and Da a diagonal operator o…
