Abstract

We have introduced an absorber structure based on metamaterials to reduce radar cross section of objects. The absorber is a periodic array with new and relatively simple design which has a thickness of 1.4 mm. The desired structure is analysed by impedance matching method. Simulation results using CST software show that this structure has a good absorption in the frequency range of 8.1 to 10 GHz in TE and TM polarizations of the Incident waves; which reduces the radar cross-section from a minimum value of 2 to a maximum value of 80 dB. The proposed absorber structure has the appropriate thickness, size and weight that using of it will improve radar cross-section reduction of the objects and will make the body of the objects stealth.
