Simultaneous control of acoustic and electromagnetic waves using metasurfaces

In this work, we propose the use of metasurfaces to create multiphysics devices for simultaneous control of electromagnetic and acoustic waves. Using an analytical model based on surface impedances, we introduce power flow-conformal metasurfaces that perform the same functionality for electromagnetic and acoustic waves. Moreover, we also explore possibilities to realize different functionalities for electromagnetics and acoustics within the same platform. We numerically simulate realistic topologies for practical implementations and confirm the viability of the proposed platforms.
