We obtain estimates for convergence rates of the eigenelements (λ ε , u ε) for the Laplace operator in a domain Ω ⊂ R 3 periodically perforated along a plane γ = Ω ∩ {x 1 = 0}. The boundary conditions are of the Dirichlet type on ∂Ω and of the Robin type, involving a large parameter O(ε −κ), on the boundary of the cavities. The small parameter ε denotes the(More)
