摘要： The present invention relates to an electromagnetic shielding sheet capable of improving reliability. Particularly, the present invention provides a composite magnetic sheet for electromagnetic shielding structured such that an independent soft magnetic sheet, which has a low surface roughness, is laminated on the outermost surface of a soft magnetic sheet having a lamination structure, thereby implementing laminated composite sheets having different surface roughness or porosity characteristics; as a result, the reliability in an external hazardous environment, such as saline water, can be substantially enhanced while maintaining the efficiency of electromagnetic shielding.

摘要： Disclosed are a soft magnetic alloy and a wireless charging apparatus including the soft magnetic alloy. The soft magnetic alloy has a chemical formula expressed as Fe100−x−yCuxBy (wherein x ranges from 0.1 at % to 1.7 at % and y ranges from 2.3 at % to 9.6 at %). Without adding any expensive alloying element, only iron (Fe), copper (Cu), and boron (B) are used to obtain a nanocrystalline soft magnetic alloy that has a low coercive force and a high saturation magnetic flux density. The nanocrystalline soft magnetic alloy is applied to a wireless power transmitter and a wireless power receiver. Thereby, it is possible to make a shield member thin and increase a power transmission capacity. The soft magnetic alloy is easily processed into a flake form. The soft magnetic alloy processed in this way is applied to the shield member. Thereby, it is possible to increase permeability in a surface direction.
