Qualitative regularities of structure of optimal composite constructions under wave influences

The problem is developed of optimal control of energetic wave influences of different physical nature (electromagnetic, acoustic, thermal, elastic) on the base of the set composite medium structure. On the base constructive analysis necessary conditions of optimality it is shown that optimal structures have row of unical properties. Knowing this universal qualitative regularities is alowed to develop effective methods of investigation of limit possibilities of composite constructions. for the control of energetic wave influences of different physical nature.
