By virtue of finite element method for solving 2-D scalar helmholtz equation combined with absorbing boundary conditions, the numerical procedures and programs of 2-D structural radar absorption materials (SRAM) structures for stealth performance are analyzed and carried out. Based on the theoretical study and algorithmic programs, the parameter optimization concepts of SRAM on the basis of frequency of inputted electromagnetic wave to attain best stealth performance are investigated as well as the target functions. The optimization algorithmic codes under sequential quadratic programming are designed and the electromagnetic parameters of three examples of 2-D single layered SRAM——two based on single frequency and one on multi-frequency of incidence electromagnetic wave, are optimized.
