摘要

We study feasible physical mechanisms for tuning the electromagnetic topological states in one-dimensional arrays of coupled dielectric resonators. We demonstrate two approaches for varying the topological properties: (i) mechanical, based on the mutual orientation of meta-atoms with a broken mirror symmetry, and (ii) thermal, based on temperature variation.
