ABSTRACT:
An insert for non-reciprocal waveguide device comprises a layer of ferrite and a layer of energy absorbing material with a spacer layer between them. The device works by reason of asymmetrical interaction of the microwave energy and the ferrite whereby energy is preferentially absorbed in the reverse direction. The spacer layer affects the distribution of electromagnetic fields so that there is a relatively low attenuation associated with one direction and a relatively high attenuation associated with the reverse direction.
