Notes:
The relative complex dielectric permittivity, ε*=ε′−iε″, of ice has been measured in the frequency range 5–39 GHz and in the temperature range 190–265 K. The cavity resonator method at 5 and 10 GHz and the open resonator method at 33 and 39 GHz were used to determine the low dielectric loss of ice. The real part of permittivity ε′ was independent of the frequency. The temperature dependence of ε′ was observed and is discussed in terms of contributions from anharmonic effects to infrared polarizability. The ε″ obtained bridges the gap of previous results between 200 and 258 K. We discuss the frequency and temperature dependence of the effect of the infrared absorption band on ε″. The ε″ variation with frequency increased as the temperature decreased at 5–39 GHz. It is possible that absorption takes place at frequencies below the infrared region. © 1996 American Institute of Physics.
