ABSTRACT:
A system of slow wave structures for coupling a first electromagnetic circuit to a second electromagnetic circuit includes an inner slow wave structure and an outer slow wave structure concentric with the inner structure. The outer structure is configured to provide for a greater phase velocity of electromagnetc waves than the inner structure, the phase velocities for each structure being proportional to the circumference of each structure so that the rate of circulation of a wavefront about the common axis of the two structures is the same for a wave propagating about the inner structure and a wave propagating about the outer structure. The structures are terminated in their characteristic impedances to provide for wave propagation in one direction without reflections.
