Journal ArticleDOI
Reprogrammable phononic metasurfaces
TL;DR: A metamaterial plate is realized that can be dynamically tuned by harnessing geometric and magnetic nonlinearities in the individual unit cells and can control the amplitude of transmitted excitation through the plate over three orders of magnitude.
Journal ArticleDOI
Acoustic Fresnel lenses with extraordinary transmission
TL;DR: In this paper, the authors investigated numerically and experimentally highly efficient acoustic lenses based on the principle of extraordinary acoustic transmission, which can transmit up to 83% of the incident energy and generate sharp focusing with very high amplification.
Journal ArticleDOI
Tunable Vibrational Band Gaps in One-Dimensional Diatomic Granular Crystals with Three-Particle Unit Cells
TL;DR: In this article, the authors investigate the tunable vibration filtering properties of statically compressed one-dimensional diatomic granular crystals composed of arrays of stainless steel spheres and cylinders interacting via Hertzian contact.
Journal ArticleDOI
Ultrastructural examination of dentin using focused ion-beam cross-sectioning and transmission electron microscopy.
Ravi K. Nalla,A.E. Porter,A.E. Porter,Chiara Daraio,Andrew M. Minor,Velimir Radmilovic,Eric A. Stach,Antoni P. Tomsia,Robert O. Ritchie +8 more
TL;DR: Two particular problems involving dentin, a structural analog of bone that makes up the bulk of the human tooth, are examined and FIB-milling was able to generate high-quality specimens that could be used for subsequent TEM examination.
Journal ArticleDOI
Electrical tuning of elastic wave propagation in nanomechanical lattices at MHz frequencies.
Jinwoong Cha,Chiara Daraio +1 more
TL;DR: One-dimensional, non-linear, nanoelectromechanical lattices (NEML) with active control of the frequency band dispersion in the radio-frequency domain (10–30 MHz), inspired by NEMS-based phonon waveguides, and includes the voltage-induced frequency tuning of the individual resonators.
