....topological mismatch between the local director on the particle surface and the uniform director at large distances, a drop with homeotropic boundary conditions will create a hedgehog director configuration in its immediate vicinity. Two defect structures can result in the case of strong anchoring [1, 2]: 1. A quadrupolar structure with a ring defect (Fig. 1) 2. A dipolar structure with a satellite defect (Fig. 2) There are no defects in the case of weak anchoring (Fig. 3) Figure 1: Particle with homeotropic boundary conditions and disclination ring. Figure 2: Particle with homeotropic ....
