This article focuses on an asymptotic expansion for the modified Helmholtz equation. The given regular and bounded domain in \(\mathbb{R}^2\) contains a hole which has an impedance condition prescribed on the boundary. The authors provide the topological derivative, which is then used for numerical simulations for the inverse problem.
