The structure is combined as herring bones from laminates or from anisotropic initial phases. These structures disperse the direction of anisotropy, and they result is either isotropic mixtures or in mixtures with lower anisotropy rate.

D_{\mbox{\footnotesize {zigzag}}}= L( R(\phi) D R^T(\phi),
R(-\phi) D R^T(-\phi), m, n_0)

where $R(\phi)$ is the rotation matrix. The construction can be repeated many times leading to a fractal geometry.

Zigzag structure

Zigzags may model the natural high order laminate structures, as in the pictures .. These structures helped to solve several optimization problems The zigzag structures are known to have:
