“…Theoretically, the microwave reflection coefficient RC (dB) [58,59] is calculated from the relative permeability and permittivity at the given frequency and absorber thickness. In a single layered absorber, the electromagnetic wave absorbing property can be evaluated by the following equation [60][61][62]:…”

“…Additionally, the tanδ of the cupric oxide-nanowire-covered carbon fibers (CNWCFs) shows two peaks when the frequency ranges are 4 -13 and 14 -18 GHz, respecttively, which indicates wide range microwave absorption in both frequency ranges according to the microwave absorption theory. The absorption frequency and bandwidth of CNWCFs decrease with the thickness increaseing and the optimum thickness of CNWCFs is 1 -1.3 mm [10].…”

Nanostructured radar absorbing materials (RAMs) have received steadily growing interest because of their fascinating properties and various applications compared with the bulk or microsized counterparts. The increased surface area, number of dangling bond atoms and unsaturated co-ordination on surface lead to interface polarization, multiple scatter and absorbing more microwave. In this paper, four types of nanostructured RAMs were concisely introduced as follows: nanocrystal RAMs, core-shell nanocomposite RAMs, nanocomposite of MWCNT and inorganic materials RAMs, nanocomposite of nanostructured carbon and polymer RAMs. Their microwave properties were described in detail by taking various materials as example

“…. Good mechanical properties of continuous carbon fibers owe them a great exploitation in the fabrication of radar absorbing structures, however, these are strong reflectors of electromagnetic waves and require variations in processing parameters, heat treatments, change in size and shape effecting their absorbing properties . The prepared carbon filaments were found to have good electromagnetic properties but were not comparable to conventional carbon fibers for their mechanical properties and DC electrical conduction .…”

Due to high specific strength, fatigue resistance, and stiffness, reinforced plastic composites have great deal of relevance in aerospace applications such as electromagnetic interference shielding, radar absorption, etc. These radar absorption structures offer good mechanical properties, absorption characteristics, and less interference with external profile making them viable for aerospace structure design. Present venture trades the investigation concerning the attenuation of electrical component (electromagnetic waves) through the inclusion of different carbon‐based absorbers in glass/epoxy. Short carbon fibers like carbon black and multi‐walled carbon nanotubes were utilized as the lossy components. The samples were manufactured via vacuum assisted resin infusion technique which gave uniform thickness and minimum void content. Particles were mixed in resin and infused in the glass preform. The effects of changing the absorber materials, number of layers of glass fiber mat and glass fiber itself were analyzed. Sandwiched absorbing structures with aramid honeycomb were also fabricated. The samples were tested via free space measurement technique. Two charts of results were obtained i.e. one with dielectric parameters and other with the reflection loss. Short carbon fibers showed the best fallouts in this study. Moreover, thickness with 16 layers of glass fiber was also evidenced as optimum for the structure. POLYM. ENG.
