Abstract :
The design, analysis,characterisation, manufacture and application of new, large area, permanently magnetised quasi-optical Faraday rotators is discussed. As isolators, these have given state of the art performance at W-band with isolations /spl sim/60 dB and insertion loss /spl sim/0.35 dB, at spot frequencies. It is believed that the wideband performance of these isolators is primarily limited by the matching of the ferrite to free space.<>
