Abstract: An attempt is made to improve the Robert von Hipple measuring method and the Present work is concern with measurement of complex dielectric permittivity, conductivity, loss tangent and penetration depth of some bio-material. The measurement makes use of Robert Von Hipple technique or short circuited waveguide method. All the measurements were made in the microwave frequency range (Experiment is carried out at 9.9 G.HZ). In the present investigation it is interesting to note that the high dielectric constant is coupled with high dielectric loss in case of biological samples which contain large quantity of water but this is not the feature of a non biological materials. The influence of vitamins and minerals on the dielectric parameter is made using a correlation calculation is made between dielectric parameters, vitamins and nutrients.
