| Abstract Scope |
.Radar is a sensitive detection tool that uses electromagnetic radio waves to determine the position and motion of the objects. Since its development, the methods for reducing radar wave reflections have been explored to improve the stealth technology. One of the methods for reducing radar reflection is coating the aircrafts by radar absorbing metamaterial. This research studies the radar absorption properties of a metamaterial honeycomb structure which has a gradient protruded inner walls that is made of a radar absorbing material fabricated with carbon nanotube (CNT)-based iron oxide composite. The CNT-based iron oxide composite materials were first prepared then electromagnetic interference (EMI) shielding measurements were conducted to obtain the permeability and permittivity values of the material. The effect of changing the geometrical parameters of the honeycomb structure (size, height, thickness and tilted angle) on the radar absorption properties has been simulated using Multi-Physics COMSOL. Simulation results showed that the optimum structure can absorb more than 90% of the radar incident waves in X-band frequencies and can reach a RL peak value of -52 dB |
