Tailoring wave-matter interactions with Mie-resonant and acoustoplasmonic metasurfaces

Imaging science is a critical enabler of revolutionary scientific advances across disciplines. However, current imaging technologies face prohibitive trade-offs in resolution, penetration depth and experimental complexity. Here, we introduce new classes of micro- and nanostructured photonic surfaces which scale down and enhance light-matter interactions, to overcome existing challenges in imaging science in a miniaturized, on-chip format. We introduce “acoustoplasmonic metasurfaces” to enable tunable acoustic wavefront shaping with polarized light. The proposed acoustoplasmonic metasurfaces merge the physics of light and sound in previously unexplored ways, opening new avenues to harness wave-matter interactions. Future applications of acoustoplasmonic metasurfaces include on-chip imaging with simultaneously high spatial resolution and penetration depth, which can enable societally relevant applications ranging from biomedicine to industrial materials, to environmental science.
