COUPLING COEFFICIENTS IN THE INHOMOGENEOUS CAVITY CHAIN

In this paper a mathematical method on the base of a rigorous electrodynamic approach for description of inhomogeneous chain of cylindrical cavities is presented. The form of the obtained for chosen amplitudes set of equations is similar to the set of equations that describe the simple coupled circuit chain. As the cavity have the infinite number of resonant frequencies, to obtain the coupling coefficients one have to solve additional infinite set of linear equations with coefficients that depend on the frequency. By using the developed method for inhomogeneous cavity chain one can take into account the dependence of the coupling coefficients on frequency and geometrical sizes of the cavities in the case of “long-range ” coupling
