Angle-dependent phase reversal through deep-subwavelength dislocation in hyperbolic metamaterials

In this communication, we show that phase-shifted transmission can be achieved through the deep-subwavelength dislocation in hyperbolic metamaterials. Based on the analysis using Fourier modal method, we show that the regime of `phase reversal´ exists for the oblique incidence which has the tangential wavevector anti-parallel to the direction of dislocation.
