Abstract
It has been already demonstrated that a coupled cavity system is well represented by a lumped constant circuit. This representation was extremely fruitful to describe the behaviour of these cavities in a bandwidth sufficiently small with respect to the central frequency. It is worthwhile to remind that, once assembled the system, the cavities loose their individuality and that the system frequency modes are generated by a rather complex cooperation of the cell frequencies. The problem that generally arises is to extract from the frequency modes all the parameters characterizing the structure, in order to predict the system behaviour in a variety of cases. This tool would allow to easily optimize the structure, once some quality index are fixed.
