Overview

Experiments reveal diverse nonlinear waves in architected structures, suggesting insights into energy harvesting and sensing.

Key Points

  • New conserved quantities in architected structures enable the control of nonlinear waves for diverse applications.
  • Evidence shows that conformal symmetry underlies a variety of nonlinear waves and low-energy surface waves.
  • Simulations highlight the dispersion of waves influenced by the structure's bulk modulus and unit cell size.
  • This research opens pathways for innovative applications in energy harvesting, sensing, and mode conversion.
