"The engineered class of periodic anti-tetrachiral materials is mainly characterized by\r\nthe unusual macroscopic property of a negative Poisson’s ratio. The auxetic behavior of the material\r\ndepends on the geometric and elastic features of the microstructure. In particular, the material symmetries\r\nof the periodic cell govern the quadratic or orthotropic symmetry of the first-order elastic\r\ntensor (i.e. auxetic quadratic or auxetic orthotropy). Under the assumption of uniform mass density\r\nand elastic properties, one or the other case can be realized by a square or rectangular microstructure,\r\nrespectively. A beam lattice model with lumped masses is employed to analyse the effects\r\nof different, usually small-valued, geometric and elastic parameters of the high- and low-frequency\r\ndispersion curves and band gaps characterizing the free wave propagation."^^ .
