1. In combination:
a ferromagnetic material; and a slow wave structure disposed to magnetically couple a magnetic field, produced by electromagnetic energy propagating through the slow wave structure, into the ferromagnetic material; wherein the slow wave structure is a transmission line having a first transmission line section disposed between a pair of second transmission line sections; wherein the first transmission line section and the pair of second transmission lines sections comprise: the first transmission line section having a strip conductor and a pair of ground plane conductors; and wherein the strip conductor comprises a first strip conductor section disposed between the pair of second transmission lines sections, and wherein the first strip conductor section is separated from a portion of the pair of ground plane conductors disposed over and under the first strip conductor section at a first distance D1, and wherein the pair of second transmission lines sections are separated from portions of the ground plane conductor disposed over and under the pair of second transmission lines sections at a second distance D2, where D1 and D2 are different distances.
