Tailoring dispersion and evanescent modes in multimodal nonlocal lattices using positive-only interactions (opens in new tab)

Author(s): Lucas Rouhi and Christophe DrozMetamaterials derive their unconventional properties from engineered microstructures, with periodic lattices providing a versatile framework for modeling wave propagation. Dispersion relations, obtained from Bloch-Floquet theory, govern how waves propagate, attenuate, or localize within such systems…[Phys. Rev. Applied 25, 064066] Published Mon Jun 22, 2026
