文摘

We realize 90° polarization rotation with both high polarization conversion efficiency and broad bandwidth by using a single layer of L-shaped particles inside a glass cube. The simulation results show that Fabry-Perot resonance effect enhances the transmission for both co-polarization and cross-polarization light in the L-shaped layer. And the co-polarization electric field component has been suppressed in the far field because of the destructive interference. The simulation results also show that the spectral band of peak polarization rotation can be shifted by changing the size parameters. This broadband polarization rotation mechanism may be very useful in designing polarization rotators.KeywordsMetamaterialsPolarizationResonance
