Prestrain-induced bandgap tuning in 3D-printed tensegrity-inspired lattice structures

Kavli Affiliate: Chiara Daraio | First 5 Authors: Kirsti Pajunen, Paolo Celli, Chiara Daraio, , | Summary: In this letter, we provide experimental evidence of bandgap tunability with global prestrain in additively-manufactured tensegrity-inspired lattice structures. These lattices are extremely lightweight and designed to exhibit a nonlinear compressive response that mimics that of a tensegrity structure. […]

Topology optimized multi-functional mechanically reconfigurable meta-optics studied at microwave frequencies

Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Philip Camayd-Muñoz, Maximilien F Debbas, Andrei Faraon | Summary: Metasurfaces advanced the field of optics by reducing the thickness of optical components and merging multiple functionalities into a single layer device. However, this generally comes with a reduction in performance, especially for multifunctional […]

Diffusing wave spectroscopy: a unified treatment on temporal sampling and speckle ensemble methods

Kavli Affiliate: Changhuei Yang | First 5 Authors: Jian Xu, Ali K. Jahromi, Changhuei Yang, , | Summary: Diffusing wave spectroscopy (DWS) is a well-known set of methods to measure the temporal dynamics of dynamic samples. In DWS, dynamic samples scatter the incident coherent light, and the information of the temporal dynamics is encoded in […]
