Tuning Elastic Waves in Soft Phononic Crystal Cylinders via Large Deformation and Electromechanical Coupling
Bin Wu, Weijian Zhou, Ronghao Bao +1
Soft electroactive materials can undergo large deformation subjected to either mechanical or electrical stimulus, and hence they can be excellent candidates for designing extremely…

Actively controllable topological phase transition in phononic beam systems
Weijian Zhou, Weiqiu Chen, Michel Destrade +1
Topological insulators, which allow edge or interface waves but forbid bulk waves, have revolutionized our scientific cognition of acoustic/elastic systems. Due to their nontrivial…
