Abstract
A microwave frequency magnetic field manipulation system 10 comprises a re-entrant microwave cavity 12 having a substantially continuous and closed internal surface 14 with at least two opposite sides 16 and 18. Two or more posts, P1, P2, . . . Pn (hereinafter referred to in general as “posts P”) are provided in the cavity 12. The posts P are in physical and more particularly electrical contact with one of the sides 16. Respective gaps G are or can be formed between free ends of the posts P and the side 18. The system 10 also has a signal source 20 coupled to the cavity 12 for supplying microwaves. The source 20 supplies microwave signals at frequencies that facilitate the generation of magnetic fields in opposite directions about at least two mutually adjacent posts P. Accordingly the magnetic field is reinforced in a common region 22 between the mutually adjacent posts P.
