Abstract

We consider Poisson problems Δuε=f-\Delta u^\varepsilon=f on perforated domains, and characterize the limit of uεu^\varepsilon as the solution to (Δ+μ)u=f(-\Delta+\mu)u=f on domain ΩRd\Omega\subset\mathbb{R}^d with some potential μW1,(Ω).\mu\in W^{-1,\infty}(\Omega). It is known that μ\mu is related to the capacity of holes when μL(Ω).\mu\in L^\infty(\Omega). In this paper, we characterize μ\mu as the limit of the density of the capacity of holes also for many μW1,(Ω).\mu\in W^{-1,\infty}(\Omega). We apply the result for the inverse homogenization problem, i.e. we construct holes corresponding to the given potential μLd(Ω)+L(δS)\mu\in L^d(\Omega)+L^\infty(\delta_S) where δS\delta_S is a surface measure.
