We consider a magnetic Schroedinger operator in a planar infinite strip withfrequently and non-periodically alternating Dirichlet and Robin boundaryconditions. Assuming that the homogenized boundary condition is the Dirichletor the Robin one, we establish the uniform resolvent convergence in variousoperator norms and we prove the estimates for the rates of convergence. It isshown that these estimates can be improved by using special boundarycorrectors. In the case of periodic alternation, pure Laplacian, and thehomogenized Robin boundary condition, we construct two-terms asymptotics forthe first band functions, as well as the complete asymptotics expansion (up toan exponentially small term) for the bottom of the band spectrum.
