Effect of salinity on dynamic dielectric properties of Sundori wood of Bangladesh

Abstract

The dynamic dielectric properties of Sundari wood have been investigated for their dependence on saline content and various thicknesses of wood slice. Measurement of capacitance and loss tangent have been carried out in the range from 1 kHz to 13 MHz (Agelent 4192 A LF) at room temperature. The calculated values of the dielectric constant at oven-dry condition were found to be between 2.69 to .086 and was increased with the wood slice thickness. These results were varied with their saline content. The introduction of salt ions into the Sundari wood matrix increases the dielectric constant by a factor of two
