The Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena β Metamaterials 2020, will comprise a 4-day Conference (28 September β October 1), and a 2-day Doctoral School (2β3 October). Co-organized by the METAMORPHOSE VI AISBL (https://www.metamorphose-vi.org) and the The City University of New York (CUNY), the Congress will provide a unique topical forum to share the latest results of the metamaterials research. 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.
