Abstract
- We study the Imbert-Fedorov (IF) effect in Kretschmann configuration with anisotropic metamaterial to explore a flexible method to enhance and modulate IF shift. The physical mechanism for large IF shifts in an anisotropic waveguide based on spin-orbit angular momentum coupling is explained. The influences of metamaterial thickness, anisotropy, and loss on IF shift are systematically discussed. This provides a theoretical prediction of IF shift in a Kretschmann configuration which is verified by simulation results in semiconductor metamaterial waveguide. The simulation results show that both metamaterial anisotropy and loss contributes significantly to the IF shift. Thus, reducing the loss and enhancing the metamaterial anisotropy are necessary and important measures to realize enhanced IF effect in the proposed Kretschmann configuration. [ABSTRACT FROM AUTHOR]
