Abstract :
In this paper, the impact of double-wall carbon nanotubes (DWCNTs) concentration within BenzoCycloButen (BCB) composites on electromagnetic properties is evaluated and modeled with coplanar test structures. It is demonstrated that only 0.37 wt. % of DWCNT concentration increases the line losses level by more than a decade over a large frequency range. The resulting engineerable composite brings to RF-designer a novel degree of freedom to design and optimize microwave innovative components.
