Abstract
Perforated screens can be used as frequency selective surfaces when a high pass frequency response is required. In this paper, a spectral characterisation of perforated screens is presented. The analysis yields the generalised scattering matrix of each screen, which is a useful tool for studying composite structures. Numerical results, relative to single and double screens with periodical distributions of circular apertures, are discussed.Keywords
