Abstract :
We study the motion of waves or quantum particles through a periodical waveguide with screens. We start with one screen and progress to periodical case. In a stripe Ω=(R{0})×[0,π]϶(x, y) we consider Laplacian with Dirichlet boundary conditions on upper y=π and lower y=0 lines, and with perturbation on a segment {0}×[0,π]. We study the self-adjoint case
