A multi band absorber using band gap structures

This paper proposes the design of a multiband absorber using EBG structures to absorb radiation in the X-band for stealth applications. It can also be used in the K and Ka bands for reduction of Electromagnetic Interference. The structure was created using Genetic Algorithm and the simulation was performed on Ansoft High Frequency Surface Solver (HFSS). The results indicate that the structure has 97% absorption in the X band at 8.2 GHz and absorbs most of the radiation in the K, Ka bands. The structure also has low RCS and hence can find use in military applications.
