Magneto-inductive waveguide

A new magnetic waveguide is described the operation of which is based on inductive coupling between resonant elements. The general form of the dispersion equation is shown. For a particular embodiment of the waveguide. consisting of 26 elements, the relative values of the currents are plotted and the travel of power from the first to the last element is shown by the streamlines of the Poynting vector. Application, as a magnetic guide for magnetic resonance imaging (MRI) is proposed.
