Abstract

The equivalent circuit model based on the average period for periodic overlapping circle metallic mesh is proposed in this paper. The equivalent reactance coefficient b in the equivalent circuit model is revised according to the simulation results of Ansoft designer software. In order to guide the optimization of the electromagnetic shielding effectiveness of periodic overlapping circle mesh, the effects of the diameter 2R and period g on the electromagnetic shielding efficiency were simulated and analyzed. The simulation results show that the electromagnetic shielding effectiveness is better than 22dB in the 2-18GHz band. The periodic overlapping circle mesh can be applied to the area where the strong shielding effectiveness,high optical transmittance and low image-degradation are required simultaneously.
