Optimal design of multilayer radar absorbing materials: a simulation-optimization approach

Multilayer radar absorbing materials with light weight, strong absorption, and wide absorption bandwidth are urgently demanded the increase of electromagnetic pollution. However, current design methods only simulation operation or optimization strategy not comprehensive. Here, a simulation-optimization approach including numerical calculation is proposed based on interaction between different software, in which homogeneous medium substitution method presented to simplify complicated structures. Besides, return loss impedance matching layer structures investigated. From simulated results, it can be found that better have superior performance. The optimal shows advantages fast efficient, has tremendous potential for various applications, such as military stealth wave elimination.
