Abstract
Problems of the optimal synthesis of multilayer structures implementing the ultimate performance under the action of elastic waves are considered. It is required to design a multilayered structure by choosing the physical properties of materials, the thickness of the layers, their number, and the mutual arrangement of layers with different physical properties in a way such that the energy characteristics of an elastic wave be as close as possible to the desired characteristics. From an analysis of the necessary optimum conditions, it is inferred that the optimal solutions are characterized by a certain internal order in the structure parameters, i.e., by an internal symmetry. When known a priori, these qualitative relations considerably reduce the number of variants tested for the optimum and make it possible to efficiently design composite structures implementing the ultimate performance in terms of exhibiting the desired properties under the action of elastic waves.
