Dynamic Willis-framework homogenization for metabeams with active scatterers

Key Points

• The dynamic analysis successfully reveals unique wave propagation characteristics within metabeams.
• Key findings indicate that the introduction of active scatterers enhances the effective performance of metabeams during propagation.
• Observational analysis using the Willis-framework provides insights into the homogenization process in complex metamaterials.
• These findings may enable the development of improved materials for engineering applications, expanding the scope of current metabeam technology.
