In the context of wave propagation through damaged (elastic) solids, an analytical approach to study the normal penetration of a scalar plane wave into a periodic array of defects with arbitrary shape is introduced. By means of a (uniform) approximation slightly stronger than the standard one-mode type, explicit analytical formulas for the scattering parameters are derived. Numerical resolution of the main integral equations for assigned shapes provide some graphs that are reciprocally compared.

Abstract
In the context of wave propagation through damaged (elastic) solids, an analytical approach to study the normal penetration of a scalar plane wave into a periodic array of defects with arbitrary shape is introduced. By means of a (uniform) approximation slightly stronger than the standard one-mode type, explicit analytical formulas for the scattering parameters are derived. Numerical resolution of the main integral equations for assigned shapes provide some graphs that are reciprocally compared.File in questo prodotto:
