Abstract

Measurements of the dielectric properties of frozen cod have been carried out in the temperature range 0 to -30°C. The technique used was a variation of Time Domain Spectroscopy, (TDS), known as the total reflection method, which employs the complete reflected pulse from a sample terminated in a 50 Ω load.  The effective bandwidth in the frequency domain was typically 3 to 100 MHz for these measurements although certain preliminary measurements were made up to 3 GHz. Changes with time were observed, particularly in the loss tangent, as was expected from previous measurements at 10 GHz. Such changes took place over periods of weeks.
