Abstract
We numerically study polarisation conversion by anisotropic metasurfaces made of electro-optic material on a silica substrate and show that we can control the polarisation of transmitted waves dynamically. We predict that such metasurfaces can exhibit tunability of the cross-polarisation conversion of linear incident polarisation as well as tunable circular dichroism. We compare the metasurface performance for direct and inverse structures and find that the cross-polarisation transmission coefficient can be tuned by approximately 0.5, while the predicted tunability of circular dichroism is close to 0.8.
