Elastic wave Talbot effect in solids with inclusions

•The Talbot self-imaging effect is demonstrated for elastic waves propagating in a homogeneous solid with periodic inclusions.•Numerical simulations are performed for various locations of gratings confirming the robust wave pattern.•An interferometer based on the elastic wave Talbot effect is discussed.

The numerical simulation of elastic wave propagation through a grating in a homogeneous medium shows the characteristic Talbot self-imaging effect. The size of the imaging and patterns can be controlled by changing the periodicity of grating and wavelength, respectively. It provides a novel route to modulate elastic wave distributions in solids with inclusions. Time dependent simulation suggests a long-distance elastic-wave-based interconnection in solids. An interferometer based on the elastic wave Talbot effect is discussed.
