Curvature Matters!
In this recent EML paper, we show the stark effect of curvature on the performance of metamaterials, both in the static and dynamic domains. Read more at: https://doi.org/10.1016/j.eml.2024.102285

Postdoctoral Position Available in United Arab Emirates on Acoustic Absorption and Vibration Damping
A Postdoctoral Research Fellow position is available immediately in the Advanced Digital & Additive Manufacturing (ADAM) Center at the Khalifa University of Science and Technology in Abu Dhabi in United Arab Emirates. Applicants should demonstrate research capabilities in investigating the acoustic absorption, vibration damping, and mechanical behavior of structural systems made of architected lightweight cellular materials and composites.
PhD positions in Wave Mechanics and Metamaterials Laboratory at the Technion (Israel)
Wave Mechanics and Metamaterials Laboratory seeks candidates with strong knowledge in magnetoelasticity, wave mechanics, finite element modeling (ideally of magneto-mechanical coupling), or strong experimental background in ultrasonics or magnetism (ideally knowing how to operate an electromagnet). For more details, pls, see attached file.
Postdoc position at the University at Buffalo – SUNY (Elastic Metamaterials)
The Sound and Vibrations Lab (http://svl.eng.buffalo.edu), directed by Prof. Mostafa Nouh at the University at Buffalo – SUNY, has an opening for a postdoc position in the areas of phononics and elastic metamaterials. The position is supported by an NSF project whose main objective is to investigate the mechanics of space-time-periodic material systems operating within asymmetric, nonreciprocal, non-Hermitian, and/or frequency-selective regimes.
Asymmetric acoustic energy transport in non-Hermitian metamaterials
One of our studies on linear and nonlinear non-Hermitian metamaterials has been published on the recent special issue of the Journal of the Acoustical Society of America: Non-Reciprocal and Topological Wave Phenomena in Acoustics.
Abstract
Architected Lattices for Simultaneous Broadband Attenuation of Airborne Sound and Mechanical Vibrations in All Directions
Since their inception, more than two decades ago, phononic crystals and metamaterials have led to advanced materials with exceptional acoustic and elastic characteristics, such as negative effective mass and stiffness. In these materials, the dispersion properties and the energy transfer are controlled by selecting the geometry of the lattices and their constitutive material properties. Most designs, however, only affect one mode of energy propagation, transmitted either as acoustic airborne sound or as elastic structural vibrations.
Student research assistant positions available at Penn State
Graduate researchers are being sought to join the Penn State Ultrasonics Laboratory, which is part of the department of Engineering Science and Mechanics at Penn State. Research topics include, but are not limited to ultrasonics for nondestructive evaluation/testing, stress waves in solids, influence of microstructure on wave propagation and scattering, diffuse field methods, acoustics applied to qualification of additively manufactured parts, acoustic microscopy, nonlinear elasticity, mechanics of soft materials, and acoustic metamaterials.
