Simulation and Application of Conductive PE Films in Dual-mode Metasurfaces

This paper presents a method for accurately setting up conductive polyethylene (PE) films with carbon coating in electromagnetic simulations and further validates the reliability of this method through their performance in reconfigurable metasurfaces. Firstly, with different material types setting in the simulation software, the electromagnetic characteristics of carbon-coated materials with sheet resistances of 20 Ω □, 120 Ω □, and 5000 Ω □ are simulated to obtain their reflection and transmission coefficients. Subsequently, the simulated material samples are placed in a waveguide, and a vector network analyzer is used for measurement. The measured results are then compared with the simulation results to identify the material setup method that most closely matches the actual properties, thereby improving the accuracy of the simulation results. Based on this, the optimal material setup method is applied to the simulation modeling of reconfigurable metasurfaces, and measurements are conducted further to validate the accuracy of the material setup method.
