Title: Dispersion in Periodic Media
Speaker: M. Vanninathan, TIFR Bangalore
Abstract: We discuss acoustic wave propagation in finely periodic media. Dispersion of small scales due to in-homogeneities is a well-observed phenomenon. The challenge is to suggest a well-posed dispersive model to capture this phenomenon.
