Abstract


Phononic properties of discrete metamaterial, made of elastic cylinders arranged on a simple square
lattice, are described analytically. The importance of the interactions between shear and rotational waves
in granular phononic crystals is demonstrated. Control of these interactions extends the opportunities for
shear wave band design in metamaterials.
