MWSW04 - Multiple scattering in engineering and applied sciences

We present novel results on the vibrations of the elastic structures composed of resonators and finite phononic crystals (PnCs) called meta-atoms. The normal modes associated to these structures get trapped inside the resonators and decay evanescently through the PnCs when the normal-mode frequencies of the resonator fall within the bandgap of the PnCs. The trapped vibrations, called atomic elastic meta-orbitals, mimic the quantum-mechanical p_z orbitals. By coupling two or more meta-atoms, artificial elastic molecules are built and the molecular elastic meta-orbitals emerge. Applications to aromatic and linear molecules are presented. Topological states, appearing in artificial elastic polymers, also emerge in the coupled-resonator elastic structures.
