Optimal synthesis of inhomogeneous layered structures
E. L. Gusev · Acoustical Physics · 2002
The optimal synthesis problem for inhomogeneous acoustic structures is studied. The case is considered when a discrete set of materials is available. A possibility for efficiently designing inhomogeneous structures that realize the ultimate characteristics of acoustic media is studied. The extremal relationships between the parameters of optimal acoustic systems are obtained on the basis of a constructive analysis of the necessary optimum conditions. These relationships can be used to study the ultimate performance of inhomogeneous acoustic structures.
