Architected Lattices with Adaptive Energy Absorption
Yifan Wang, Brian Ramirez, Kalind Carpenter +3
Energy absorbing materials, like foams used in protective equipment, are able to undergo large deformations under low stresses, reducing the incoming stress wave below an injury or…

Observation of nonreciprocal wave propagation in a dynamic phononic lattice
Yifan Wang, Behrooz Yousefzadeh, Hui Chen +3
Acoustic waves in a linear time-invariant medium are generally reciprocal; however, reciprocity can break down in a time-variant system. In this Letter, we report on an experimenta…
