| Abstract: | Reported is a numerical calculation of near-field and far-field intensities for two electrowetting microprism designs. This includes an investigation of one-dimensional, two-dimensional, and bi-prism pixellated arrays. The diffraction efficiency of an incident Gaussian beam is investigated. Far-field deflection angles are extended to more than 10°. For the phased arrays the diffraction angles are discrete and the angles between the diffraction peaks can be covered by applying a tilted phase to the input field. |
