“…If the phase difference between interacted waves at the boundaries of plate is equal to zero the pressure amplitude will be = P:'i and the energy flux for each region will equal the halfofthe full flux. But ifthe opposite wave comes to the boundary 11-111 with some phase difference (in comparison with boundary I-Il) the solution of system in general case (4) gives us different wave amplitudes. In other words, amplitude of the wave passing through the plate is modulated by opposite wave amplitude and confined in range from Pb -Pj to Pb + Pf .…”

The problem of opposite interaction of longitudinal acoustic waves in dissipative media was considered, for instance, for plane parallel isotropic plate and onedimensional periodic structure. All results were obtained for the normally incident waves. The boundary conditions of continuity were used to take into account repeated reflection. The questions of energy conservation were paid attention to in order to consider correctly the possibility ofenergy loss diminishing. The positive test result corroborated our method to be right. The analyses of dependence carrying through the investigated dissipative medium flux for different pressure amplitude ratio and phase difference were carried out. The numerical analysis allowed to propose the use of the opposite waves interaction for the control by energy flux passing trough the dissipative media by means of changing of opposite source intensity and phase difference between interacting waves. The result can also be applied to the qualitative control ofperiodic structures.
