From: Singular observation of the polarization-conversion effect for a gammadion-shaped metasurface

(a) Azimuth angle and (b) ellipticity angle of the output polarization state of the first-order diffracted light transmitted from the G215 nanostructure with a gammadion shape under different input linear polarization states. The red dots are the experimental results and the black dots are the simulated results.
