We have used computer simulations to predict that the beam-steering efficiency of a common liquid-crystal diffraction grating will depend on which side is presented to the incident beam. The finite-difference time-domain method and the Helmholtz–Kirchhoff diffraction integral were utilized to simulate the performance of an idealized configuration of the grating.
