Acoustoplasmonic metasurfaces for next-generation imaging applications

Metasurfaces are composed of sub-wavelength periodically arranged resonant structures that can manipulate wave-matter interactions in manners not observed in nature. All-optical and all-acoustic metasurfaces have separately demonstrated versatile capabilities such as lensing, beam steering or wavefront control. Here, we study a new class of acoustoplasmonic metasurfaces. By combining the physics of light and sound in previously unexplored ways, this platform enables entirely new avenues to harness the power of wave-matter interactions. This work paves the way toward versatile societal imaging applications ranging from environmental science to biomedical devices or industrial imaging.
