The Ninth International Congress on Advanced Electromagnetic Materials in Microwaves and Optics – Metamaterials 2015, will comprise a 4-day Conference (7–10 September), and a 2-day Doctoral School (11–12 September). Co-organized by the Metamorphose Virtual Institute and the University of Oxford and hosted by the University of Oxford, this Congress follows the success of Metamaterials 2007-2014 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 TLC. The Congress will provide a unique topical forum to share the latest results of the metamaterials research in Europe and worldwide and bring together the engineering, physics, and material science communities working on artificial materials and their applications from microwaves to optical frequencies, as well as in acoustics, mechanics, and thermodynamics. The Doctoral School collocated with the Conference will represent an excellent opportunity for students and young researchers to get exposure to the latest advancements in the field of metamaterials and to meet the leading experts in this rapidly developing field.
