Does Rayleigh anomaly occur only in metals?

17 April 2020 0 3K Report

Surface plasmon polaritons (SPPs) and Rayleigh anomalies (RAs) are two characteristic phenomena exhibited by periodic grating structures made of plasmonic materials .

Indium Antimonide (InSb) exhibits plasmonic properties such as metals at THz. Does Rayleigh anomaly occur in InSb at THz ?
