The scope of this work is to evaluate and highlight metamaterials properties and their possible applications in automotive field. Starting from a general overview of metamaterials characteristics the work will follow a practical approach with the attempt to reproduce the study presented in the paper “Metamaterials for simultaneous acoustic and elastic bandgaps” by Waiel Elmadih, Dimitrios Chronopoulos & Jian Zhu. The simulation software chosen to perform the analysis is COMSOL Multiphysics® since it allows to design the material, shape it and perform very accurate studies in vibroacoustic scenario. The work commenced with the digital design of a single metamaterial unit cell, for an investigation into its structural properties.
