Abstract
Microwave radar absorbing properties are effectively achieved due to the unique structure and electrical properties of nanostructured materials. The main objective of the present work is to show that by utilizing lower weight fractions of MWCNTs an efficient and thin microwave absorber with load bearing capacity can be developed. Fibre reinforced polymer (FRP) nanocomposites for radar absorbing applications in the X-band (8.2–12.4 GHz) were prepared using MWCNTs as dielectric lossy material. The complex permittivity values obtained from Vector Network Analyzer were used to evaluate the reflection loss of double-layered structures using transmission line theory. A reflection loss of less than −10 dB for entire band was obtained for RAS 8 with a total thickness of 3 mm. At central frequencies of 10.6 GHz and 11.0 GHz RAS 6, RAS 3 shown −32 dB and −35 dB, respectively, corresponding to 99% absorption of incident electromagnetic radiation. The proposed double-layered RAS are lightweight promising structures for radar absorption application.
