Abstract
The operation of current-access magnetic bubble domain propagate circuits has been simulated successfully by using a previously developed numerical scheme. The drive field has been given analytically as ![H_{Z}(X,Y,Z) = - H_{p}\\cos[2\\pi(X/R_{X} - n(T)/4)]\\exp[-(Y/R_{Y})^{b}]](/images/tex/9154.gif)
after a dual-conductor-sheet device which has bit period RX and track width in the order of 
. A method of testing bubble propagation with minimum length of the simulated time lapse has been established for both s = 0 parallel-azimuth and s = 1 uni-chiral bubbles. Margin diagrams in terms of drive-field amplitude Hp and dc bias field have been obtained for both bubbles at a drive frequency of 1MHz. The principle of calculation and the results of the simulation are given.
