PROJECT TITLE :

Microstructure Design Method for Multineedle Whisker Radar Absorbing Material

ABSTRACT:

Multineedle whisker radar absorbing material (RAM) could be a new quite stealth nanocomposite, whose radar absorbing property could be a perform of microstructure. The availability of appropriate simulation models taking account of the microscopic structure of such fascinating composite is important for its style and performance optimization. In this letter, a unique simulation model is presented to carry out the microstructure design for improving radar absorbing performance of multineedle whisker RAM. Initial, this computational model is established in step with equivalent medium theory and transmission line methodology. Then, calculative curve is compared to existing experimental data, and sensible agreement suggests that the proposed model will be a useful tool for microstructure optimization of this type of RAM. Finally, the microstructures of a three-layer multineedle zinc oxide whisker (M-ZnOw) RAM are optimized by using the simulation model and particle swarm algorithm, and the numerical results demonstrate the potential of microstructure design for improving the radar absorbing property of such fascinating composite.
