Anomalous Light Scattering by Topological PT-symmetric Particle Arrays
Robust topological edge modes may evolve into complex-frequency modes when a physical system becomes non-Hermitian. We show that, while having negligible forward optical extinction cross section, a conjugate pair of such complex topological edge modes in a non-Hermitian [Image: see text]-symmetric s...
