Linear-polarization metasurface converter with an arbitrary polarization rotating angle
Optics Express, 2021 This paper presents a new design of linear-polarization metasurface converter with arbitrary polarization rotating angle. The linear-polarization conversion is achieved by first separating the linearly polarized incident wave into two orthogonal circularly polarized waves, then adding an additional phase to one of the circularly polarized waves, and ...

Planar Polarity: Converting a Morphogen Gradient into Cellular Polarity [PDF]
Current Biology, 2015 Epithelial cells are polarized within the apico-basal and planar axes. The latter - planar cell polarity - requires long-range regulation of orientation as well as short-range, cell-to-cell realignment through feedback loops. New insights into the long-range, gradient-type regulation reveal how a kinase translates the morphogen gradient input into ...
