Abstract: We study the periodic Imbert-Fedrov (IF) shift in a prism-coupling waveguide with epsilon-near-zero (ENZ) metamaterial. We take into account the influence of ENZ meta material and gold layer thicknesses as well as the metal material on the IF effect in our proposed waveguide. The calculation method is derived and theoretical analysis is given. Based on simulation results, we can find periodic IF shifts can be observed which provides us an opportunity to realize enhanced IF effect at various incident angle. Further calculations shows that ENZ metamaterial thickness determines the maximum IF shift value, the periodic property and incident angle corresponding to IF shift peak. However, the metal thickness and permittivity only has an important influence on maximum IF shift value which will not affect the periodic property and incident angle corresponding to IF shift peak.
