Reconstruction for an inverse scattering problem with a Kerr type nonlinearity

Khaoula El Maddah, Matti Lassas, Tony Liimatainen +2

We study the inverse scattering problem for the Kerr-nonlinear Helmholtz equation \[ Δu + k^2(1+q(x)|u|^2)u = 0 \quad \text{in }\mathbb{R}^n,\; n\geq 2, \] where the aim is to reco…
