Abstract
A structure may include a rotational element having a fixed central point and rotational freedom. A structure may include one or more branches connected to a tangent of the rotational element and extending outward therefrom, wherein the unit cell repeats throughout the structure; and wherein the unit cell allows rotational movement of the rotational element and prevents translational movement of the rotational element.

A structure for zero-frequency absorption comprising a unit cell formed from an elastic material, wherein the unit cell comprises:
- a rotational element having a fixed central point and rotational freedom;
- and
- one or more branches connected to a tangent of the rotational element and extending outward therefrom;
- wherein the unit cell repeats throughout the structure;
- and
- wherein the unit cell allows rotational movement of the rotational element and prevents translational movement of the rotational element.
A structure for zero-frequency absorption comprising:
- a plurality of unit cells, each unit cell comprising a rotational element having a fixed central point and rotational freedom, and one or more branches connected to a tangent of the rotational element and extending outward therefrom, wherein the plurality of unit cells are connected by the one or more branches;
- and
- solid pins passing through the fixed central point of each of the plurality of unit cells.
