Plate lattices exploit planar elements that achieve near-optimal isotropic mechanical properties and yet other physical properties. The introduction of customizable perforations enables Helmholtz resonance for superior acoustic properties and tuneable flow properties, while closed cells provide high thermal resistance. Hybrid plate lattices further create broadband vibration bandgaps from regions of high and low masses. These combined advantages establish plate lattices as uniquely multifunctional solutions for advanced engineering applications.
