FIG. 1.

Position of CNTs captured at different times in both the cells at the frequency of . (a) Positions of CNTs captured at 0°, 25°, 119°, 180°,192°, 299°, and 360° phase angles of input sine wave in homogeneous aligned cell driven by in-plane field. The direction of the motion of the CNTs in homogeneous aligned cell driven by in-plane field is in the plane of the paper. (b) Positions of CNTs captured at 0°, 25°, 119°, 180°, 192°, 299°, and 360° in homeotropic aligned cell. The direction of the motion of the CNTs in homeotropic aligned cell is perpendicular to the plane of the paper. (c) Theoretically plotted graph for velocity (continuous line) and displacement (dashed line) of CNTs in LC medium as a function of time. The magnitude of velocity of the CNTs in the dielectric medium is maximum, at the phase angles of 90° and 270° and zero at 0°, 180°, and 360°.
