These matrices indeed satisfy the chirality criteria of equation (1) within the ∼ 1% uncer- tainty evaluated from the degree of purity of the Mueller matrice of the empty setup.

## III. DISCUSSION AND CONCLUSION 

To illustrate the polarization conversion properties of our chiral structures, we compare in Fig. 2 theory and experiment when the input state is linearly polarized and when the output transmitted intensity is analyzed along different orthogonal directions. A good agreement between the measurements and the theoretical predictions deduced from the Jones matri-
