Scattering diffusion control of electromagnetic and acoustic fields by multi-physics coding metamaterials

Digital coding metamaterial is a frontier interdisciplinary aiming at building up the connection between physics and information science. Although the coding metamaterial has attracted a lot of attention in the community of microwaves, terahertz waves, and even acoustic waves, so far there is no counterpart for multi-physics. In this paper, we introduce the coding principle to the multi-physics realm, which can manipulate wave behaviors of both electromagnetic and acoustic waves. As an application, we demonstrate a novel device to control the scattering diffusion of the multi-physics fields. The investigation may provide inspirations to design multiple physical interaction systems in the future.
