摘要：Values of dielectric constant (ε’ ), dielectric loss (ε’’), relaxation time (τ), conductivity (σ) of Pearl millet (HHB 62) were measured at room temperature at four different frequencies viz 4.65 GHz, 7.00 GHz, 9.35 GHz and 14.98 GHz in microwave region, using two point method and employing a specially designed dielectric cell for powders. Also, effect of variation of moisture content on dielectric properties of Pearl millet in powder form was studied at room temperature at 9. 35 GHz.. Both, the dielectric constant and loss factor are found to decrease with increase in frequency and to increase with increase in moisture content. The present values of dielectric constant are in good agreement with the values reported by other authors.
