COMPLEX DIELECTRIC-CONSTANT OF ICE AT 1.8 GHZ

The complex dielectric constant of bubble-free ice grown from deionize d water was determined at 1.8 GHz using an interference technique. The interference pattern was produced by measuring the reflected signals from bubble-free ice slabs of varying thickness at normal incident ano le. The wavelength and loss factor in the bubble-free ice samples were obtained from the resulting interference pattern. The real and imagin ary components of the dielectric constant were determined to be 3.17 a nd 0.003, respectively.
