Dielectric Properties of Rice Husk/Carbon Nanotubes Composites in Ku-band
This paper presents the dielectric properties of rice husk and carbon nanotubes (RHCNTs) composites materials. The RHCNTs composites materials prepared with various weight ratios of rice husk with CNTs 0-10 wt%. The length, width, and thickness of each RHC-NTs composite sample are 15.799 mm, 7.899 mm, and 5mm was fabricated. The rectangular waveguide technique was used to measure the complex relative permittivity of the RHCNTs composites materials. The conversion of s-parameters to complex relative permittivity parameter is computed by using 85071E Agilent technology software which using a transmission line technique consists of a network analyzer to perform the conversion to complex relative permittivity, r. The complex relative permittivity is represented in terms of both the real and imaginary parts of permittivity in Ku-band frequency. The conductivity of RHCNTs shows increasing when the ratio of CNTs mixture increases. The materials, their dielectrics properties measurement result over 12.4-18 GHz frequency range are discussed.
