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

Dielectric Relaxation in the Electric Double Layer
TL;DR: In this article, two groups of phenomena can cause frequency dispersion of capacity and resistivity at a perfectly polarizable interface: penetration of the electrolyte to shielded parts of the electrode and the resulting transmission line phenomena are discussed.

Velocity of radio waves in ice by means of a bore-hole interferometric technique
TL;DR: In this paper, radio waves of fixed frequency, which had passed through ice and firn from a transmitting antenna lowered down a bore hole, were monitored on the surface by mixing the received signal with the fixed frequency to give a value for the wavelength in ice at the depth of the antenna.

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.
