Emissivity and Dielectric Behavior of Red Soils of Dhule District at X-band Microwave Frequencies
Abstract: Using X-band (8.2 and 10.5GHz) experimentation, the fluctuation of the dielectric constant (ε’) and dielectric loss (ε’’) of soil samples with different moisture contents has been determined. After reaching a transition point, the value of (ε') grows gradually with moisture content before increasing quickly after that. The emissivity has been estimated from experimentally determined (ε’) using emissivity model for vertical polarization. The findings indicate that as MC/dielectric constant increases, emissivity …
