Nanomaterials in Radar Absorbing Materials design using Particle Swarm Optimization and Genetic Algoritm

This work presents the design and optimization of a Radar Absorbing Material system in the X-Band frequency. Radar Absorbing Material is required in some military and aerospace systems in order to reduce the radar detection/visibility, Stealth technology is the most known application. Two different evolutionary algorithms are applied and results are shown and compared to each other. Algorithms are Particle Swarm Optimization and Genetic Algorithm. Multilayer structures optimized by the algorithms are based on carbon nanostructured composite materials. Nanomaterials and micromaterials used are Carbon Nanotube, Carbon Nanofiber, Fullerene, Micrographite. Differences in absorption performaces for composite absorber based on micromaterials and nanomaterials are reported showing better performances of nanomaterials and absolute best performances when both nanomaterials and micromaterials are adopted. At the end the future activities related to frequency band extension and fre-space measurement of absorption properties are reported.
