Dielectric properties of black soil with organic and inorganic matters at microwave frequency

Abstract

The dielectric properties of black soil have been studied with addition of organic (vermi compost) and inorganic (calcium carbonate) matter. Microwave transmission line waveguide technique has been used for this purpose. The dielectric properties [dielectric permittivity ( Ɛ') and dielectric loss ( Ɛ'')] have been measured for four different frequencies at room temperature. The experimental observations show that Ɛ' and Ɛ'' decrease with increasing frequency of oscillation, and increases with increasing percentage volume of organic and inorganic matter. The results show that dielectric values obtained with organic matter are higher than that of inorganic matter.
