Phononics 2017: The 4th International Conference on Phononic Crystals/Metamaterials, Phonon Transport/Coupling and Topological Phononics
Abstract
Achieving extremely low frequency stop band has been one of the most important challenges. Here, we propose a new way to achieve extremely low frequency stop band for flexural waves, which we call a zero rotational stiffness. The physical background of our new idea will be presented with numerical supports.
