Abstract :
The potentials of the waveguide-below-cutoff technique for the realization of circulators are discussed and performance limits outlined. Two realizations are presented showing either narrow-band performance in conjunction with extremely high attenuation outside the pass-band or moderate bandwidths of 10 to 15 per cent.
