To achieve wave control at broad-band ultra-low frequencies, we design "accordion-like" meta-structures by periodically alternating tensegrity prisms with solid disks. The structures are characterized by extremely wide band gaps, which can be tuned by varying the level of prestress in the constituent elements. They provide valid alternatives to other metamaterials with low-frequency performance, the functionality of which relies on a locally resonant mechanism, by overcoming an inherent limit of narrow operating frequency ranges and demonstrating the resilience to variations in geometric and material parameters.
