International audienceThe present work is concerned with a numerical description of the wide band vi-bratory behavior of a set of coupled elastic and dissipative complex periodic systems-each system is composed, along a specific direction, of identical substructures. The kinematic quantities (displacements, forces) of each system are described from the wave modes propagating along the direction of periodicity. The frequency evolution of each mode is analyzed (evalu-ation of the dispersion curves). The diffusion properties (reflection and transmission) of the modes of different systems coupled through an elastic element are formulated.Cette étude propose une description numérique du comportement vibratoire large bande d'un ensemble de systèm...
