Modeling of Multi-layer Microwave Absorber Structures for radar cross section

In this paper, radar absorbent materials with complex permittivity and permeability coefficients are studied. A novel swarm algorithm called Imitation-base Swarm Optimization is proposed to solve the Rardar Absorbent Nano-Material problems. It is suggested that each individual in the swarm explores the search space for better positions. It is shown that our proposed method gives better and high quality results and numerous applications are foreseeable for it. The program is capable of arranging and prioritizing the layers. It can choose the optimum layer thickness and do the modeling for different frequency and incidence angles. Reflection losses are analyzed at the microwave range for different angles. This code can also be used for the case of both the electric and magnetic polarizations.
