Simulation and Analysis for Electromagnetic Shielding Performance of Magnesium

magnesium and magnesium alloys are green engineering materials for 21st century. In the paper, the model of electromagnetic shielding performance of Magnesium is built according to different media around magnesium. If magnesium is plated on engineering plastic board, the simulations show that the property of magnesium to reflect electric-field component is a little better than the property of magnesium to reflect magnetic-field component. Whether magnesium is surrounded with air medium, or magnesium is plated in engineering plastics board, the total shielding effectiveness of magnesium varies with thickness of magnesium and frequency of electromagnetic wave.
