Abstract
Director configurations for inverted nematic emulsions with axial symmetry are evaluated. In particular, a chain of two water droplets in a sphericall y confined nematic solvent is investigated by employing the finite element technique. We confirm an experimental observation that the distance d of th e point defect from the surface of a water droplet scales with the radius g amma of the droplet like d = 0.3 gamma. When the water droplets are moved a part, we find that the point defect does not stay in the middle between the droplets, but rather forms a dipole with one of them.
