Figure 2
Sequence of structures for the symmetric transition scenario in increasing electric field \(e=|{\mathbf {E}}|d(\varepsilon _0\Delta \varepsilon /4K_{11})^{1/2}\). Experimental cross-polarized microscopy images for (a) symmetry axis perpendicular to the plane, \(N_0=2.2\), and (b) symmetry axis parallel to the plane, \(N_0=1.8\). Simulated cross-polarized images (c) and director distribution in primary cross cuts (d–f) for E7, \(N_0=2.5\). Hereinafter, double arrows indicate the direction of the polarizers, and the director \({\mathbf {n}}\) is colored in correspondence with the direction (red along the x-axis, green along the y-axis, blue along the z-axis).
