000014143 520__ $$2eng$$aWaves in periodic media undergo dispersion, namely the propagation velocity depends on the frequency. This effect can be modeled by an additional term in the homogenized wave equation. This paper presents the estimation of upper and lower bound of the dispersive effect in the two-dimensional wave equation in the case of an 8-fold symmetric periodic microstructure with constraints of volume, perimeter and homogenized properties.
