Theories are given for periodic rectangular arrays of perforations in rigid and thin elastic plates. The perforations contain identical dynamical systems, terminated by rigid pistons, which are represented by an impedance matrix. The excitation is a plane wave at arbitrary incidence. At low frequenc
