EDP : Patrick Ciarlet (ENSTA) : How to solve problems with sign-changing coefficients
Bâtiment Sophie Germain, salle G210This talk summarizes joint works by the speaker and Anne-Sophie Bonnet-Ben Dhia, Lucas Chesnel, Camille Carvalho and Juan-Pablo Borthagaray on how to solve problems with discontinuous, sign-changing coefficients. In electromagnetic theory, the effective response of specifically designed materials is modeled
