✦ Synopsis

The propagation patterns are deliniated by ion implantation in the top layer of.the bubble garnet material. The magnetic domains are displaced by the charged walls created around the disks under the influence of an in-plane field. The shape of these contiguous elements allows a tenfold increase in storage dqnsity when compared to the conventional asymmetric permalloy chevrons. The operation of the different elementary functions necessary for a working chip is described, as well as th~ technological process necessary for its fabrication. The possible chip architectures are reviewed with their respective performances.
