Abstract

Controlling and steering elastic waves through isotropic material slabs is of particular interest in engineering applications. This can be achieved by using acoustic holograms. Elastic wave manipulation through solid structures remains a challenge for locally charging sensors or devices. Unlike fluid mediums, wave propagation through solid structures involves the propagation of longitudinal and shear waves that need to be accounted for when designing the hologram. Numerical simulations and experiments are conducted to verify our approach and to show the capability of holograms to pattern elastic waves. This work was supported by the U.S. National Science Foundation (NSF) under CAREER grant No. CMMI 2143788, which is gratefully acknowledged.
