Interactions of two humps of dipoles in anisotropic nonlinear media

Propagation of dipoles and superposed dipoles in anisotropic nonlinear medium is investigated. The two humps of the dipoles will repel each other if attraction between them is smaller than repulsion, while if the former is larger than the latter, they attract. If there is phase gradient on the input dipoles or the energy distribution of the dipoles does not along the boundary directions of the medium, the dipoles will exhibit incomplete rotation during propagation.

► There are attraction and repulsion between the two humps of the dipoles simultaneously.
► If the former is smaller than the latter they will repel each other, while if larger they attract.
► If there is phase gradient on the inputs, the dipoles will rotate during propagation.
► If energy distribution does not along the boundary directions of the medium, dipoles will also rotate.
