Abstract
A device for changing the divergence of a beam of microwave radiation comprises a ferrite body having an aperture through which the beam passes. Magnetic wires pass both through the body and across the aperture, or a magnetic coil on either side of the aperture, causes a differential phase delay as the beam passes through the aperture which broadens or narrows the beam.
