Abstract
Method and apparatus are provided for selectively tailoring electromagnetic fields, and in particular for providing rapidly vanishing magnetic far-fields for magnet arrays, coils and the like. The method involves selectively combining magnetic, coil or other arrays having fields that vanish as 1/r.sup.l to achieve and array having a selectively increase l value. Various techniques for achieving such combinations in one, two or three dimensions, and the arrays resulting from such combination are disclosed.
