Abstract:
A method for tailoring electromagnetic fields such that the field has a smallest l value equal to l' and greater than two, including the steps of:(a) combining an N'th field source, possessing an N'th moment and an N'th l value less than l', with an M'th field source, possessing an M'th moment and an M'th l value less than l', to obtain a combination of field sources, wherein the N'th and M'th moments have substantially equal magnitudes and opposite signs, the N'th and M'th l values are equal, and the combination is an (N+1)'th field source possessing an (N+1)'th moment and an (N+1)'th l value that exceeds the N'th and M'th l values by one; and(b) comparing the (N+1)'th l value with l' and, if the (N+1)'th l value is less than l', incrementing N and M by one and repeating steps (a) and (b).
