Signal propagation in a bubble lattice with long range dipole interaction

The propagation of an information bit along a dense packed bubble lattice is simulated by computer. Each column of bubbles is assumed to be a non-linear oscillator interacting with other ones by short and long range dipole forces. The results show how a bit, represented by a transition layer separating two regions of differing response, moves through the lattice with velocity depending on the amplitude of the external driving force and on the ratio between short and long range interactions.
