摘要：

The scattering cross section of an elastic plane wave incident at right angle to a circular cylinder was calculated. The frequency dependence of this single scattering cross section is connected to the existence (or not) of spectral gaps for elastic waves propagating in a periodic array of parallel circular cylinders. The present work confirms the picture of propagation along two distinct channels: one employing mainly the host material and the other exploiting the resonance modes of each cylinder.
