After three years of intense research activity, the Aerialist Project came to its end. The Final Meeting of the project has been held in the form of an online meeting due to the complicated situation and public health measures concerning the COVID-19 pandemic the 30th June 2020. All the partners presented to the Project Officer and to the panel of experts the project activities and the outcomes of the various work packages, with a particular focus on the advancements achieved in the second part of the project. During the Mid Term meeting, the experts gave their advice and recommendations which have been fruitfully followed, leading to excellent scientific results.All the work package contributed to the production of an extensive literature, with more than 30 scientific works, among papers published in international journals and presented at the most relevant international congresses of the sector. These publications hold the advancements Aerialist achieved in the field of aeroacoustic metamaterials in terms of theoretical and...
