Description
Seung Han Kim and colleagues propose in 2026 a new building-block design for materials that steer waves in unusual ways. Some engineered materials link each cell to far-off cells, not just neighbors, which creates odd wave patterns. Scaling those designs up, and keeping wave types from mixing, has been hard.
Their platform, called Metaspire, stacks units in a sequence of rotations to create those long-range links. Worked examples trace wave motion around special features known as maxon and roton points. Symmetry effects on bending waves get close attention too. Built samples matched the design goals, showing wider scaling and cleaner separation between wave modes than earlier attempts allowed.
