Abstract

Abstract: Recently, artificially structured metamaterials (MMs) are proposed to manipulate the wave propagation behaviors in single physical domain. However, the multiphysics manipulation is rarely reported and remains a challenging issue to be investigated. Here, the design of MMs with simultaneous controls of acoustic and electromagnetic (EM) waves is presented. A double‐membrane structure is proposed to meet the need of acoustic‐wave insulation, and patterned anisotropic meta‐atoms on the membrane are employed to generate polarization‐dependent functions of EM waves. The designed structure is validated numerically and experimentally, suggesting a new route for joint modulations of acoustic and EM waves in the engineering.
