摘要

This paper focuses on analyzing the effectiveness of shielding against an electromagnetic field using a rectangular waveguide model simulated in Ansys HFSS software. The simulation was performed using a waveguide within a frequency range of 7.5–12.5 GHz (X-band). Different polymer materials including polystyrene (PS), polyethylene, polyvinylidene fluoride, polyacrylonitrile, and polyethylene, along with their fillers, were chosen for the simulation. The shielding effectiveness and reflection losses of the materials were subsequently evaluated using their thickness and conductivity. Electromagnetic simulations were conducted to investigate the impact of thickness variations on the scattering parameters (S-parameters) and, consequently, on the reflection loss of these materials. PS and polylactic acid (PLA) showed a promising increase in reflection loss, making them suitable for radar-absorbing materials in aerospace industries. The results provide valuable insights into the electromagnetic shielding capabilities of these materials under different conditions, aiding in the design and optimization of electromagnetic interference shielding materials in aircraft applications.
