On bandgap sensitivity to three-to-one internal resonances between acoustic and optical waves in metamaterials

Laura Di Gregorio, Walter Lacarbonara

We investigate the nonlinear equations governing wave propagation across a metamaterial consisting of a cellular periodic structure hosting resonators with linear and cubic springs…
