Observation of full-parameter Jones matrix in bilayer metasurface

open access: yesNature Communications, 2022
The realization of Jones matrix with full eight free parameters is particularly challenging. Here, the authors construct spatially varying Jones matrix with eight free parameters by cascading two-layer metasurfaces and use it for new optical ...
