Thin films of carbon-nano materials (CNMs) of different morphology have been successfully deposited on creamic substrate by CVD at temperature 800℃, 850℃ and 900℃ using plant based oils in the presence of transition metal catalysts(Ni, Co and Ni/Co alloys). Based on the return and insertion loss, microwaved absorption properties of thin film of nanocarbon material are measured using passive micro-Strip line componenets.
