Functional Materials for Acoustics
We engineer and study new functional materials for acoustics and use them to control wave propagation. We are especially interested in composite materials (periodic, random, locally resonant or with gradients of properties). These materials can enable tunable wavefront control or exhibit extraordinary scattering and absorption properties. We achieve high-fidelity propagation control with practical materials that can find applications in the development of advanced devices for complex wavefront shaping, ultrasonic imaging, sound attenuation or acoustic stealth. Another aspect of our research focuses on the mechanical effect of sound waves interacting with distant targets. We are developing new strategies to trap, manipulate and deform soft and biological matter without any physical contact.
