Frequency multiplexing with dispersion-engineered elastic metasurfaces.

ABSTRACT: Distinguishing the frequency components of elastic waves is essential for ensuring the stability of mechanical systems. Herein, a frequency-multiplexed elastic metasurface is introduced, utilizing a dispersion engineering. The proposed dispersion-engineered elastic metasurface multiplexes frequency-dependent phase profiles, enabling frequency-selective wavefront tailoring. The phase profiles of the meta-atoms, derived from Kirchhoff-Love plate theory, are controlled solely by the plate thickness, eliminating the need for a typically required extensive meta-atom library or complex optimization. Integrating the metasurface with a piezoelectric element converts the focused elastic energy into an amplified electrical signal. Therefore, the magnitude of extracted energy alone reveals the underl
