On the Fréchet derivative in elastic obstacle scattering
In this paper, we investigate the existence and characterizations of the Fréchet derivative of solutions to time-harmonic elastic scattering problems with respect to... -
Fast spectral methods for the shape identification problem of a perfectly con...
We are concerned with fast methods for the numerical implementation of the direct and inverse scattering problems for a perfectly conducting obstacle. The scattering... -
Nonlinear approaches for phase retrieval in the Fresnel region for hard X-ray...
The development of highly coherent X-ray sources offers new possibilities to image biological structures at different scales exploiting the refraction of X-rays. The...
