THIS GRANT IS A CONTINUATION of N000141410388 HELICOIDAL PHONIC CRYSTALS: A NEW BUILDING BLOCK FOR DESIGNING NOVEL MATERIAL SYSTEMS
Abstract
The research will seek to design, fabricate, and characterize a new class of tunable materials that are capable of controlling propagation of one mechanical wave mode via another via phonon-phonon interactions. Control of this phonon-phonon scattering will be done by employing helicoidal architectures of nonlinear lattices, called helicoidal phononic crystals (HPCs). The phonon-phonon coupling mechanism in the proposed systems can open a new avenue in filtering, switching, and mitigatingmechanical waves by controlling and exchanging energy among different wave modes. Dr. Yang will aim specifically to (i) establish an analytical and numerical foundation of dynamically tunable HPCs and (ii) design and fabricate proof-of-concept prototypes of HPCs in multi-dimensions for experimental verifications.
