MICROWAVE FERROELECTRICS

Abstract

Several batches of Ba0.5Sr0.5TiO3 1% SrSnO3 ceramic were prepared and those which were measured all exhibit a slightly larger nonlinearity than pure Ba0.5Sr0.5TiO3 material. One sample only shows a markedly larger nonlinearity which was confirmed by repeated measurements and by using different measuring techniques. The reason for its superiority over supposedly identical materials was not established. Losses in other doped materials were measured. The field de pendent loss in Ba0.5Sr0.5TiO3 material was measured and an upper limit set upon its value. The value of the field dependent loss is small compared with the intrinsic zero-field loss at X-band, at 150 degrees C and for fields of 16,000,000 volts/metre.
