Effect of Size and Temperature on Dielectric Parameters of Pigeon and Chick Pea at Microwave Frequency

Ganesh Ghodmalle, Prashant Gawali

Abstract: The dielectric properties are measured by using x-band microwave bench reflectometer technique. Dielectric values are calculated at different temp. (20oc to 50oc) and packing density and then compared with co-relation formulae. There was a good agreement is found between theoretical and experimental values of dielectric parameters. The result shows there was a systematic increase in ?' and ? with increasing value of ?r and decrease in ?' and ? with increasing temperature.
