This congress series, initiated by the European Network of Excellence Metamorphose and organized by the Virtual Institute for Artificial Electromagnetic Materials and Metamaterials, and Rome International Workshops on Metamaterials and Special Materials for Electromagnetic Applications and Telecommunications, aims to provide a platform for sharing the latest research on metamaterials. It will bring together experts from various disciplines, including engineering, physics, applied mathematics, and material science, who work on artificial materials and their applications in electromagnetism/optics, acoustics/mechanics, transport, and multi-physics.
