Abstract

We study the propagation of waves in an elastic matrix containing a doubly periodic array of coated circular cylindrical inclusions. The aim is to find band gaps, intervals of frequency for which the waves do not propagate. We show that ar­rays of inclusions, consisting of a core and a coating, exhibit band gap properties for elastic waves. In particular, results show that by choosing appropriate elastic parameters for the coating we can create a composite structure which acts as a homogeneous material in the low frequency range.
