Enhanced Transmission of Plasmonic Waveplates with a Periodic Array of Nanorectangles
Abstract
Plasmonic waveplates with enhanced transmission can be achieved in the proposed structure with a periodic array of nanorectangles. Based on the model of nanoslits, both the transverse electric (TE) and transverse magnetic (TM) waves can be transmitted through the nanorectangles, enhancing the transmission of the incident polarized light. Simulation results show that the transmission ratio and phase shift of TE and TM waves can be manipulated by the nanorectangles structures, enabling plasmonic waveplates with enhanced transmission.
