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...
متن کاملEffect of various parameters on electromagnetic shielding effectiveness of textile fabrics
The effect of material type, yarn count, pick density, type of mordant and layers of fabrics on the electromagnetic shielding properties of textile materials has been studied. The shielding effectiveness of the fabric is measured by estimating the insertion loss incurred to the signal when the sample is placed in the path of the signal at the frequency range 100 MHz-3 GHz inside the coaxial tra...
متن کاملEffect of weight reduction pre-treatment on the electrical and thermal properties of polypyrrole coated woven polyester fabrics
Weight reduction increased the amount of deposited polypyrrole (PPy) on the polyester (PET) fiber surface, leading to a considerable decrease in electrical resistance and improved heat generation capacity for the PPy coated PET fabrics. Application of DC voltages to an insulated roll of PPy-coated fabric increased the temperature to about 90 oC. This showed the suitability of these fabrics for ...
