METAMATERIAL IN ACOUSTICS, ELASTODYNAMICS AND ELECTROMAGNETISM - Advanced School

Du 12 juillet 2021 au 16 juillet 2021

Udine - Italie

Advanced School coordinated by Habib Ammari - ETH-Zurich, Switzerland Agnès Maurel - Institut Langevin, Paris, France HYBRID FORMAT

The purpose of this course is to provide an introduction to well known techniques and to introduce more advanced, state-of-the-art techniques, able to tackle the challenges of the metamaterials by providing a mathematical framework able to explain the observed extraordinary properties of meta- structures and useful to help optimize these properties. These include transformation optics/ transformation elastodynamics, classical and modern homo- genization methodologies, asymptotic and spectral analysis, variational methods, layer potential techniques, as well as modern multi-mathematics. Particular attention will be paid to present practical applications that illustrate the workings and effectiveness of the introduced techniques and discussions on the breakthroughs and the remaining open questions on topical issues in acoustics, electromagnetism, elasticity and in the context of water waves. Bearing these objectives in mind, academic experimental studies as well as commercial devices will be presented during the course.
Overall this is a joint effort from a diverse group of lecturers working on different aspects of metamaterial modelling, to report the current state-of-the-art in the field and form ......
