Abstract. Engineered metamaterials for precise wave manipulation and control is a new challenge for many applications in the field of mechanical vibration control and energy harvesting. Inspired by the advancement in wave manipulation and localization performance of elastic waveguides thanks to the introduction of resonators, we try to assess if these systems can be applied also into the junctions between beams that make up lattices. The goal is to achieve control over elastic wave propagation and define whether the local resonators are able to enhance the redirection of the wave into a perpendicular beam. Furthermore, evaluations concerning elastic energy localization in the resonators are reported to assess whether these systems are also suitable for energy localization and energy harvesting.
