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.
