Dielectric spectroscopy data measured for Foxtail Millet in powder form with temperature variations are presented. The dielectric behavior is discussed with respect to important variables. A brief review of measurements on these materials and description of the methods are included. Single frequency range for the data at 9. 8 5 GHz using X-band Microwave bench used. Values of the dielectric constant and loss factor with frequency and temperature are shown graphically, and the influences of dipolar relaxation, conductivity, dielectric loss factor, dielectric constant are discussed. The Experimental values and Calculated values from LLB formulae are verified and there is good agreement found.
