The goal of this document is to provide a comprehensive description of the equations governing the propagation of an electromagnetic lightwave trough an opening. The latter is first considered as isolated and then integrated within a periodically arranged array. The material in which the openings are drilled is supposed to be non-magnetic. No other specific assumptions are made on the optical indices of the different regions involved in order to keep this study as general as possible.

Mots clés: leaky modes; periodic array; leaky waveguide; Maxwell's equation
