Freiburg, Germany Ops, sorry, it is me that did not understand the question. But - could you give a reference for the formula? I understand that it is commonly used, and it looks vaguely familiar (SP resonance is present, and something that looks like it comes out from the periodicity - by the way what is the meaning of i and j?) - but I have never made anything with hole arrays and I do not know exactly where it does come from.
