About us

Welcome to the Laboratory of Wave Engineering !

Be it of electrical nature (microwaves,optics), or of mechanical nature (acoustics,elastics), wave propagation is at the core of modern technologies, with applications including information processing, sensing, imaging, telecommunications, and energy transfer and management. We focus on unveiling the mechanisms that govern wave interactions with complex environments and artificial materials, and apply our science to tackle challenging applications, including:

– Wave-based information processing leveraging disorder, topology, non-Hermiticity, non-reciprocity, or non-linearity.

– Acoustic imaging and sensing in challenging noisy, lossy, or disordered environments.

– Ultracompact devices to efficiently emit, manipulate, guide or detect waves at scales smaller than their wavelength.
