ABSTRACTPermittivity measurements from 0.2 to 20 GHz were taken on fresh peaches of three varieties at three stages of maturity during the growing season to determine whether dielectric properties might be correlated with maturity. Other physical properties of the peach tissue, such as density, moisture content, firmness, and total soluble solids content, were also determined. Two indices, based on dielectric constant and loss factor values at 0.2 and 10 GHz were found to correlate with stage of maturity, but they were dependent on the variety, and further study is necessary to determine their practical usefulness.

AbstractResonant coaxial SMA microwave permittivity sensor is introduced. It is constructed using only commercially available SMA connectors. The sensor is tested in two different frequency ranges for two different dielectric constant ranges, from 1 to 10 and from 10 to 80. Presented sensor is designed, fabricated, simulated, and tested. Good agreement between simulations and measurements is shown. The sensor is also applicable for differential permittivity measurements.
