Abstract
THE complex permittivity (χ'–jχ") of a series of titanates, magnesium, calcium, strontium and barium, has been measured at 21° C. and frequencies of 1·5 and 9,450 Mc./s., and of the barium titanate at 24,000 Mc./s. also. In addition, the behaviour of barium titanate at 1·5 and 9,450 Mc./s. has been studied over the temperature-range + 20° to + 170° C. The results of these measurements are recorded in the accompanying table and diagram. The electric field-strength applied to the test specimens was estimated as less than 1 volt/cm.
