Phononic crystals: Rotational modes Research We developed a lumped model for rotational modes in phononic crystals. It reveals the origin of the rotation modes, and provides a simple understanding of the mechanism. OverviewDetailsRotational modes in phononic crystals can be excited by shear waves. We started from the mass-spring description and developed a lumped model for rotational modes in phononic crystals. This model successfullyreveals the origin of the rotation modes: finite size effect and divergence freeprovides a simple understanding of the mechanismpredicts the dispersion relationCollaboratorsProf. Jun Mei, Prof. Zhengyou Liu, Prof. Chunyin QiuPublicationsPai Peng, Jun Mei and Ying Wu "Lumped Model for Rotational Modes in Phononic Crystals" arXiv 1208.6526
