Contiguous disk bubble propagation elements are known in which the lithography of the device is relaxed with respect to conventional gapped propagation elements. Coarse propagation elements can be used for moving very small bubble domains, which in turn allows the use of photolithography rather than electron-beam or X-ray lithography. However, as the bubble size decreases, the ratio h(c)/P of the cusp height to disk periodicity becomes more critical. This is illustrated in Figs. 1A, 1B and 2A, 2B.
