A Unit cell (0) of an artificial phononic crystal for building of artificial phononic metamaterials, especially applicable in the field of railroad and tramway protection and for railway track components for reduction of mechanical vibrations, is disclosed, with sufficient vibration attenuation abilities needs an optimized space-saving geometry. This is reached by each metal strut (4, 4', 4"...) is connected to a connection point (A) at the underside (10) on a first straight line (A1) at an radius (r1, ..rn) from a rotation axis (Z) protruding to the connection points (B') at the upper side (20) on a second straight line (B2) at the same corresponding radius (r1, ..rn) from the rotation axis (Z), while projection in x-y plane of first straight line (A1) and second straight line (B2) of each metal strut (4, 4', 4"...) includes a intersection angle (φ) defined by length of metal strut (4, 4', 4"...) and radius (r1, ..rn) and distances between rotation axis (Z) and connection points (A, B') of each metal strut (4, 4', 4"...) in x-y plane are equal, and each metal strut (4, 4', 4"...) is individually rotated around rotation axis (Z) such that, the longitudinal extension of each metal strut (4, 4', 4"...) is oriented to be tangential to the associated radius (r1, ..rn) in projection in the x-y plane.
