Comparison of Dielectric Constant & Loss Factor for Preliminary, Oven Dried and Saturated Grains Using Ku Band Microwave Frequency

Akhil Kumar Jain

The paper speaks to the investigation of dielectric constants alongside their loss factor for different sorts of grains which characterize their reactions against electromagnetic energy at various microwave frequencies by absorbing, radiates, reflect, and disperse a segment of electromagnetic energy. Estimation of dielectric consistent and loss factor have made for different specimens of grains, for example, Rice, Wheat, Split Red Gram (Arhar), Bengal Gram (Chana), Green Gram (Moong) for three unique states as preliminary, oven dried and saturated at various gravimetric moisture content in scope of CJ Band at two different frequency values (5.30 and 6.60 GHz) and furthermore in the scope of X Band at frequency of 10.65 GHz by utilizing waveguide cell (short-circuited lines or double minima or two point) technique. The general lab measurements are similarly critical in recognizing the grains and relatively increase the characterized crop productivity by using microwave remote sensing applications. The analytical study of various grains and pulses at microwave frequencies may give data about the vegetation field and furthermore distinguishes their behavioral properties. The examination of a capacity of cereals and pulses to absorbing emits, disperse, and reflect a part of an electromagnetic field is found by determining dielectric constant and fluctuation with the real factors. Accordingly, estimation of dielectric steady are made for different specimens of grains, for example, Rice, Wheat, Bengal Gram (Chana), Green Gram (Moong), Split Red Gram (Arhar) for three particular stages named as preliminary, oven dried and saturated at various gravimetric moisture content for Ku Band at 12.8 GHz. By utilizing waveguide cell (short-circuited lines or double minima) technique estimations have been made, includes focusing of microwaves over the specimen in a rectangular waveguide cell and fundamental standards engaged with it. The general research center measurements are assuming indispensable part to identify the grains and enhancing crop yield by utilizing microwave remote detecting applications. This paper introduces the data with respect to the impact on the essential variables influencing the dielectric properties of the agricultural products, and for detecting the quality characteristics of the agricultural products.
