Metamaterials, or media with time and spatial dispersion: a new approach to the analysis of composites with contrast

Talk by Prof. Dr. Kirill Cherednichenko

Date: 13.10.21  Time: 16.15 - 17.15  Room: Online ZHACM

I shall discuss a novel approach to the homogenisation of critical-​contrast periodic PDEs, which yields an explicit construction of their norm-​resolvent asymptotics. A practically relevant outcome of this result is that it interprets composite media with micro-​resonators as a class of (temporally and spatially) dispersive media. This is joint work with Yulia Ershova and Alexander Kiselev.
