S‐parameters, electrical permittivity, and absorbing energy measurements of carbon nanotubes‐based composites in X‐band

Composites based on carbon nanotubes (CNT) have recently received great attention as a possible new generation of radar absorbing materials (RAM), due to their efficient microwave attenuation capacity and low density. However, RAM performance can vary significantly depending on the CNT being used. Aiming to directly show the influence of CNT from two different suppliers, both multi‐walled and non‐functionalized (CNT‐B and CNT‐K), the...
