【 摘 要 】

The Present work is concerned with the measurement of the complex dielectric permittivity, conductivity, and loss tangent and penetration depth of some vegetables and jamun frouit.. The measurement makes use of the "Von-Hipple method" for bulk sample. If the sample is not available with the dimension of the wave guide then reflectrometry technique is used for the pulverized (Powder) form of the sample and computed all the above parameters and relaxation time for the sample Jamun Seed (Scientific Name of Jamun is Syzygium cumini Lin). The measurement were performed for different packing densities at 9.85 GHz. at different temperature (20°c, 35°c and 50°c). The result was correlated with Landau-Lifshitz-Looyenga and Bottcher. There is fair agreement between the calculated values of dielectric parameters and the values obtained experimentally for solid bulk and pulverized one.
