Abstract Using a single substrate. we demonstrate a simple two-dimensional (2-D) phase grating cell with an octothorp electrode. Owing to the large spatial phase difference in any direction. the proposed grating cell has a high haze value in the opaque state (76. https://www.markbroyard.com/deal-time-gtech-airram-mk2-k9-roller-roll-brush-bar-filter-vacuum-cleaner-hot-on-sale-best-find/
