Creating dynamical materials as a problem of control

The idea of creating dynamical materials is put forward in the paper. Dynamical materials are the media whose material parameters (density, elastic, dissipative and electromagnetic characteristics) change both in space and in time. When those changes take place in microscales one can speaks of dynamic composites. The appearance of time as an additional variable makes it possible to obtain the media with unusual properties very important in practice. Some of these possibilities and ways of their realization in technology are considered in the paper. Problems of control arising in this connection are also described here
