Complex dielectric constants have been measured for ice from the melting point to −65°C, and for solid D2O to −35°C, by a combination of bridge and transient methods. For both, the dispersion is described by the simple Debye formula, and the relaxation times τ by the simple rate expression τ = A exp(B/RT). For ice, A = 5.3×10−16 sec, B = 13.2 kcal/mole; and for solid D2O, A = 7.7×10−16 sec, B = 13.4 kcal/mole. The equilibrium dielectric constant for ice is 91.5 at 0°C and increases at lower temperatures; the values for solid D2O are only slightly smaller. Measures taken to minimize errors from voids in the sample and direct current conductance are discussed.read more

Glenn S. Smith,Ronold W. P. King +1 more
TL;DR: In this article, the authors used the resonant linear antenna as a probe to measure the electrical properties of dissipative media, and derived the length and driving point resistance of the antenna in terms of the relative permittivity and loss tangent of the ambient medium.

A Wide Range Capacitance‐Conductance Bridge
Robert H. Cole,Paul M. Gross +1 more
TL;DR: In this paper, the authors describe a bridge for reasonably accurate measurement by direct balance of capacitance and conductance in the frequency range 50 c/sec. to 5 cm/sec., and over most of this range is essentially direct reading in the two admission components with negligible unbalance from lead effects or guard circuits of the unknown.
