The Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena – Metamaterials'2019, will comprise a 4-day Conference (16–19 September), and a 2-day Doctoral School (20–21 September). Organized by the METAMORPHOSE VI AISBL (www.metamorphose-vi.org), this Congress follows the success of Metamaterials 2007-2018 and continues the traditions of the highly successful series of International Conferences on Complex Media and Metamaterials (Bianisotropics) and Rome International Workshops on Metamaterials and Special Materials for Electromagnetic Applications and Telecommunications. The Congress will provide a unique topical forum to share the latest results of the metamaterials research in Europe and worldwide. It will bring together the engineering, physics, applied mathematics and material science communities working on artificial materials and their applications in electromagnetism/optics, acoustics/mechanics, transport, and multi-physics.
