In this paper some of the analytic and numerical techniques that have been applied to the array interaction problem will be reviewed. For problems where high accuracy is not required, many modelers have used an approximation for the mutual interactions that has come to be known as the Pritchard approximation. In this paper a new approximation technique will be presented which appears to be more accurate than the Pritchard approximation for the cases that have been examined. Results will be shown that compare this new approximation scheme both with the Pritchard approximation and with more accurate numerical computations. [Work supported by SPAWAR PMW-182.]
