Abstract (en)
A microwave beam steering device comprises a block (1) of ferromagnetic material across which a magnetic field gradient is applied, using coils (9N, 9S, 11N, 11S) within the block. Microwave radiation incident on the block in a direction perpendicular to the field gradient is deflected, the direction ( theta ) and extent of deflection being dependent on the magnetic field. <IMAGE>
