Abstract:Compared to traditional radar absorbing materials, circuit analogy absorbing materials can be better to
reduce the material thickness, to improve absorbing properties, often the genetic algorithm is used to optimize the re鄄
sults. For the disadvantages of the conventional genetic algorithm, crossover probability and mutation probability is
improved, and the idea of “Simulated Annealing Algorithm冶is introduced as the acceptance criteria of the offspring.
The improved genetic algorithm only needs to evolve 100 generations to obtain the optimal solution, and the average
reflectance is -15. 0420 and the thickness of the material is only 1. 425mm, which are better than the result of con鄄
ventional algorithms. The results show that the improved genetic algorithm makes the convergence faster, and easy to
avoid falling into local optimal solution.
