Abstract
A beam steerer for steering a microwave beam comprises a body of magnetic material having an aperture and magnetic coils for applying a gradient of magnetization across the aperture. Tapered slots extending from the magnetic coils towards a central region of the aperture are filled with a material having a lower magnetic permeability than the magnetic material of the body. Lower reluctance paths available through the central region of the aperture allow more magnetic flux from the magnetic coils to penetrate through the central region than would be the case in a body of uniform material composition.
