Under mild conditions on the interface of the pore the Lippmann-Schwinger equation is well-posed, but ill-conditioned. Introducing a fictitious soft material renders the problem well-conditioned again. We will discuss the exact rate of convergence of these regularized problems to the porous problem.en003006519conference paper
