Tailoring four-ligament chiral metamaterials: wave propagation mechanisms mediated by the secondary ligament

Puntos clave

• Wave propagation mechanisms are significantly influenced by the additional secondary ligament of the metamaterials.
• Experimental results highlight that these mechanisms can enhance the mechanical properties by at least 30%.
• Investigation employed a systematic approach to analyze the dynamics of the ligaments in the metamaterials.
• Such findings may enable innovative designs in engineering applications, requiring further detailed study on real-world applications.
