Relationship between Reflection Coefficient and Moisture Content of Oil Palm Fruit Using an Open-Ended Rectangular Waveguide Technique

The thesis describes the development of an open-ended waveguide technique for the determination ofof complex permittivity and moisture content of the oil palm fruits of various degree of fruit ripeness. The operating frequency of the waveguide operate betweenwas between 8 GHz and 12 GHz. A theoretic...
