Implication

Simulation study demonstrates anomalous flexural wave reflection in thin plates using beam-type elastic metasurfaces, indicating a compact route for vibration control.

Key Points

To develop an ultra-thin beam-type elastic metasurface capable of anomalous reflection and deep-subwavelength steering of flexural waves in thin plates.
Formulated an analytical model based on coupled flexural-longitudinal wave motion and solved reflection coefficients using the transfer matrix method.
Designed a phase-gradient supercell using the generalized Snell's law and validated 2D and 3D metasurface models via finite-element numerical simulations.
Demonstrated an ultra-compact profile with a thickness of only 1/49.5 of the incident flexural wavelength while spanning an almost complete 2π reflection phase with high reflection amplitude.
Achieved precise redirection of normally and obliquely incident flexural-wave Gaussian beams toward predetermined anomalous reflection directions.
