Optimization of connection architectures and mass distributions for metamaterials with multiple resonators

Metamaterials with multiple resonators have been widely investigated for the purpose of generating stop bands or broadening attenuation bandwidth. The could be connected end to in a line, namely, in-series connection, individually host structures, in-parallel connection. This paper investigates influence resonator connection methodology on frequency response functions metamaterial beams and exhibits an approach optimizing their distribution over structure. receptance various architectures are calculated by transfer matrix model, which is verified through finite element model results. It demonstrated that interconnection great impact global dynamic properties metamaterials. An optimization strategy subsequently proposed find out optimal mass distributions minimize maximal targeted single ranges. objective within ranges solved adoption genetic algorithm method. weighted sum method used gain solution multi-frequency range optimization. methods demonstrate greatly enhanced vibration at frequencies interest compared other beams. work expected provide necessary theoretical basis incentive future researchers working design metamaterials extended, tuned, optimized bands.
