An embodiment of an electronic device includes a circuit component (e.g., a transistor or other component) coupled to the top surface of a substrate. Encapsulation is formed over the substrate and the component. An opening in the encapsulation extends from the encapsulation top surface to a conductive feature on the top surface of the component. A conductive termination structure within the encapsulation opening extends from the conductive feature to the encapsulation top surface. The device also may include a second circuit physically coupled to the encapsulation top surface and electrically coupled to the component through the conductive termination structure. In an alternate embodiment, the conductive termination structure may be located in a trench in the encapsulation that extends between two circuits that are embedded within the encapsulation, where the conductive termination structure is configured to reduce electromagnetic coupling between the two circuits during device operation.

A magnetic field shield having a plurality of tunable resonant loops arranged on a planar support medium. The resonant loops are loaded with a lumped component such as a capacitor or variable capacitor and produce magnetic null points. The location of the magnetic null points may be moved three dimensionally about the planar support medium.

A negative potential inducing device has a box body, an AC/DC converter, a booster, a second wire, a lid and an insulating rod. The box body has a side wall, and the side wall has a via. The AC/DC converter is arranged inside the box body, and electrically connected with a plug through a first wire. The booster is arranged inside the box body and electrically connected with the AC/DC converter. The second wire passes through the via, wherein one end of the second wire is electrically connected with the booster. The lid covers the box body. A metal wire on another end of the second wire is exposed and inserted to one end of the insulating rod and touches the insulating rod.

The present disclosure provides a protective enclosure for electronic systems. The enclosure comprises a polymer-containing matrix and a metamaterial incorporated into the matrix. The metamaterial is tuned to a specific permittivity or permeability to absorb or reflect a particular frequency. The protective enclosure may be used to create a safe inner environment for electronic components while facilitating uninterrupted wireless communications to/from the outer environment. Additionally, the protective enclosure may be used to protect against electromagnetic interference. In particular, shielding metamaterials are configured individually or in combination to specifically shield (via reflection, absorption, etc.) against relatively wide bands of electromagnetic frequencies, while transparent metamaterials are configured specifically to pass electromagnetic signals within narrow bands of frequencies. This new approach resolves and vastly improves current shield solutions, such as Faraday cages. For example, tuned metamaterials may be configured across a variety of preconfigured frequencies, and can be constructed of lightweight materials.
