Measuring the Shielding Performance of Materials
Principles and applications are described for a new method for measuring the shielding performance of materials. The new method avoids the problems of common mode signal linkage to observations circuits, is fair to materials of various constructions and provides the basis for matching shielding performance to specific practical applications.
متن کاملElectromagnetic 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 کاملComposite 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 ...
متن کاملA review on neutron shielding performance of nano-composite materials
Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...
متن کاملCathinone Neurotoxicity (“The “3Ms”)
Synthetic cathinones are designer drugs of the phenethylamine class, structurally and pharmacologically similar to amphetamine, 3,4-methylenedioxymethamphetamine (MDMA), cathinone and other related substances. New analogues, legal at least, until formally banned (a time consuming process), are introduced almost daily The United Nations estimates nearly 250 new drug analogues are produced per ye...
