Abstract: We study pulse propagation in one-dimensional chains of spherical granulesdecorated with small grains placed between large granules. The effect of thesmall granules can be captured by replacing the decorated chains by undecoratedchains of large granules of appropriately renormalized mass and effectiveinteraction between the large granules. This allows us to obtain simpleanalytic expressions for the pulse propagation properties using ageneralization of the binary collision approximation introduced in our earlierwork Phys. Rev.
