Abstract
The problem of opposite interaction of longitudinal acoustic waves in dissipative media was considered, for instance, for plan parallel isotropic plate and one-dimensional 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 of energy 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 through 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 of periodic structures.
