Tailoring Structure‐Borne Sound through Bandgap Engineering in Phononic Crystals and Metamaterials: A Comprehensive Review (2022, methodology): “[113,183,203] adopted the same design to theoretically and experimentally demonstrate ultra-low frequency LR BG using homogeneous and composite cylindrical pillars made of soft rubber with lead cape, distributed on an aluminum plate (Fig.”
Theoretical and Experimental Study of Locally Resonant and Bragg Band Gaps in Flexural Beams Carrying Periodic Arrays of Beam-Like Resonators (2013, background): “By mounting periodic arrays of local resonators to structural waveguides, such as rods [27,28], beams [29–32], and plates [33–35], a variety of LR-type periodic structures were proposed, showing the existence of LR band gaps.”
