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.

A reconfigurable multi-stack inductor formed within a semiconductor structure may include a first inductor structure located within a first metal layer of the semiconductor structure, a first ground shielding structure located within the first metal layer that is electrically isolated from and circumferentially bounds the first inductor structure, and a second inductor structure located within a second metal layer of the semiconductor structure, whereby the second inductor structure is electrically coupled to the first inductor structure. A second ground shielding structure located within the second metal layer is electrically isolated from and circumferentially bounds the second inductor structure, whereby the first and second inductor generate a first inductance value based on the first ground shielding structure and second ground shielding structure being coupled to ground, and the first and second inductor generate a second inductance value based on the first ground shielding structure and second ground shielding structure electrically floating.

Embodiments discussed herein refer to electric vehicle charging ports having integrated contactless communication units (CCUs). The electric vehicle charging ports include male and female connector assemblies that can be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connector assemblies are coupled together, power connections are made in combination with establishing contactless communications links between counterpart CCUs in both connector assemblies. The fixed alignment of the connector assemblies ensures that contactless communication channels, spanning between the connector assemblies, are aligned to enable consistent and reliable operation of contactless communications. The CCUs, which conduct contactless communications, may be integrated in the connector assemblies at fixed positions that enable CCUs of one connector assembly to be aligned with CCUs of another connector assembly when they are coupled together.
