Spectroscopic ellipsometry-based investigations into the scattering characteristics of topologically distinct photonic stopbands

Topological band theory provides a framework to establish the equivalence/inequivalence of bandgaps in photonic topological insulators. However, experimental discernment of bandgap topological characteristics encounters inherent measurement complexities, particularly beyond the terahertz frequencies...
