Abstract
In this research, a special kind of nano-composite (Terpolymer nanocomposite engineered carbon−fabric−mat: 3D-TNECFM) metamaterial have investigated as X-band stealth technology composite for the first time. Doctor-blade-coating technique was utilized for the fabrication of (Ni–NiFe2O4: 10-40 wt%) nano-composite engineered carbon-fabric-mat. X-band Radar frequency (RF) measurement was conducted via Vector network analyzer (VNA), VNA result suggested that the induced RF radiation-absorption in X-band (10 wt% (1 mm)) was −44.37 dB at 8.8 GHz and −42.78 dB at 11.6 GHz. This significant radiation absorption result was highest among all samples in X-band frequency and is attributable to the plasmonic oscillations instigated antiresonance associated with unusual mode permeability and permittivity characteristics. Further, this result supports the passive-load-impedance-matching, which can be computed by Smith chart in Computer Simulation Technology (CST) Microwave studio, and the computed impedance value was about 5.8-j46.1 Ώ (10% Ni–NiFe2O4) at X-band. Thus, simulated artillery-brick model holds best Radar cross-section (RCS) value, which was −78.6 dB m2, i.e., 0.00208 m2 (∼1/500) of its original shape in X-band at an incident angle of 90°. Therefore, authors believe that the nano-composite engineered carbon fabric-mat could be a prominent passive metamaterial for Stealth technology.
