An analytical design theory for field-access bubble domain devices

A model of magnetic bubble propagation patterns using surface charge embedded in a minimum domain configuration

“…C p + c p . p -h l * p (7) with respect to each component of p , where h is a Lagrange multiplier. This minimization can be performed by solving the simultaneous equations…”

“…M AGNETIC BUBBLE device models have been based on numerical procedures [ 1 ] - [6] , and also on an analytical approach [7] - [9] . Only the numerical models are able to treat propagation pattern shape in sufficient detail to reduce significantly the amount of expelbent necessary for device design.…”
