- 論文の詳細を見る
Horner et al's method of dielectric measurement at microwave region has been extended so that it can be applied for cylindrical specimens of arbitrary cross-sections with relatively high loss tangent and high permittivity. Small amount of Specimen is good enough for our method. As the first application of our method, dielectric constants of BaTiO_3 single crystal have been measured from room temperature to 170℃ at a frequency of 3.3KMc/s. Above the Curie point, dielectric constants measured at 3.3KMc/s agree well with those measured at 24KMc/s by Benedict and Durand, while the loss tangents slightly above the Curie point are 0.01±0.007 in our case compared to 0.1 in the case of Benedict and Durand.
