Figure 1: Kaminer et al. showed that shape-preserving beams of light that travel along a circular trajectory emerge as solutions to Maxwell’s equations. (Left) Calculated propagation of a self-bending beam. This solution assumes the wave’s electric field is polarized in the transverse direction (TE polarization).
