| Abstract: |
| In the optimization of traditional multi-layer absorbing materials, the
existing Particle Swarm Optimization(PSO) algorithms have slow convergence and
low accuracy. In order to improve the convergence speed and optimization accurac
y, based on the multi-layer absorber computational model of the transmission li
ne method, an improved simplified particle swarm optimization method(ISPSO) is a
pplied to optimize the multi-layer absorbing materials. The simulation results
show that the reflection coefficient is below -22.98 dB within 08～6 GHz
. Compared with the original literature, the optimal results are excellent. |
