Dielectric Response of <i>Borassus flabellifier</i> Wood at Different Moisture Content

Abstract

The dielectric properties for Borassus Flabellifier BF wood were determined in the longitudinal and perpendicular directions of fibbers at different moisture content. The wood parts of male and female Borassus Flabellifier tree were taken from where the natural liquid Neera collected overnight. The wood parts were dried by microwave oven from 25 percent moisture content to oven dried condition. The dielectric parameters were measured by four-probe method. All the measurement was taken on frequency 105 Hz at room temperature 3110K. The Results indicate that the longitudinal values were nearly same as perpendicular directions of fibbers for both dielectric properties and dielectric conductivity with moisture content. In this study the drying of wood done by microwave energy using a continuous microwave drier was compared to that by conventional method. Characterization of the samples was made by scanning electron microscope (SEM) Model JEOL JSM5400. The specimen’s were collected from Dhar Dist. (M.P.) India.
