Asymptotic formula for detecting inclusions via boundary measurements

Khalifa Khelifi, Mohamed Abdelwahed, Nejmeddine Chorfi, Maatoug Hassine

Abstract:
In this article, we are concerned with a geometric inverse problem related to the Laplace operator in a three-dimensional domain. The aim is to derive an asymptotic formula for detecting an inclusion via boundary measurement. The topological sensitivity method is applied to calculate a high-order topological asymptotic expansion of the semi-norm Kohn-Vogelius functional, when a Dirichlet perturbation is introduced in the initial domain.
