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.
