Electromagnetic Shielding Property of Cfrp Composite Laminates

Composite Materials for Electromagnetic Interference Shielding

This paper demonstrates that the addition of chemical agents and carbon fibers to cement can greatly enhance the shielding effectiveness of the concrete. In addition to improving the shielding effectiveness, carbon fibers and chemical agents enhance the tensile and flexural strengths significant ly. As both carbon fibers and steel fibers are electrically conductive, both can be added to cement ...

Electromagnetic Shielding Effectiveness Evaluation For Materials

The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in material. The proposed approach consist in a PSpice model using transmission line model to simulate the attenuation introduced by a material characterized by the macroscopic parameters ε, μ, σ. To verify the data obtained through PSpice simulation, a wave-guide-based measu...

Simulation of Avionics Electromagnetic Shielding Effectiveness Based on Modal Mom

In this paper, an efficient technique based on modal method of moments (MoM) is presented, the influence of apertures’ shape and calculation point of SE on electromagnetic shielding effectiveness has been studied. A very good agreement among the simulation results of the proposed technique, results available in the literature and experimental results is observed. The results of the present anal...

Influence of fabric density on shielding effectiveness of electromagnetic shielding fabric

In this paper, fabric density influence on the shielding effectiveness of electromagnetic shielding fabric is studied. A series of blended shielding fabrics are tested using a waveguide tube testing method to obtain the shielding effectiveness with different density. Experimental results show that the shielding effectiveness increases with the increase of fabric density, and there are two rapid...
