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…
Shape-morphing architected sheets with non-periodic cut patterns
Paolo Celli, Connor McMahan, Brian Ramirez +5
We investigate the out-of-plane shape morphing capability of single-material elastic sheets with architected cut patterns that result in arrays of tiles connected by flexible hinge…
A camera for single pixel acoustic compressive sensing in air
Jeffrey S. Rogers, Charles A. Rohde, Matthew D. Guild +3
Acoustic imaging typically relies on large sensor arrays that can be electronically complex and often have large data storage requirements to process element level data. Recently,…
Generation of topologically diverse acoustic vortex beams using a compact metamaterial aperture
Christina J. Naify, Charles A Rohde, Theodore P. Martin +3
Vortex waves, which carry orbital angular momentum, have found use in a range of fields from quantum communications to particle manipulation. Due to their widespread influence, sig…
