High-Precision Hybrid FA-PSO Based Inversion of Building Material Parameters for Fundamental Wireless Performance Evaluation
Zhuowei Li, Yalei Zhu, Hanqing Zhang, Sui Li, Meng Chen, Tong Zhang, et al.
In this paper, we propose an inversion method based on the firefly particle swarm optimization (FA-PSO) algorithm to estimate the permittivity, conductivity, and thickness of building materials using the free-space method. To improve convergence efficiency and robustness, an adap…
