Schematics of cell construction of metasurface liquid crystal is shown. (a) in the absence and (b) in the presence of of external electric field, the alignments of nematics are different. Schematics of a reflective metamaterial twisted mematics cell are shown, when (c) no external voltage is applied and (d) an AC voltage is applied. Vertical polarization of an incident beam experiences different reflective resonances upon reflecting from the metamaterial bottom alignment layer [14]. Schematics of a cVMS-TNLC cell is shown with a y-polarized incident light, when (e) no external voltage is applied and (f) an ac voltage is applied. Linear polarization states are orthogonal for ordinary and extraordinary refractions [9]
