EMI-shielded planar inductor for high-frequency PCB power
This technology is a flat, compact inductor — a standard component in electronics that stores and regulates electrical energy — built into a printed circuit board and surrounded on all sides by a conductive shield. The shield wraps around the top, bottom, inside, and outside of the coil windings, containing the electric fields that would otherwise radiate outward and interfere with nearby components. By integrating the shielding directly into the PCB structure, the design eliminates the need for bulky external EMI containment and enables tighter, more reliable electronic assemblies. This is particularly relevant for power electronics where high-frequency switching creates aggressive electromagnetic interference.
What you could build
A drop-in planar inductor component or PCB design module sold to power electronics manufacturers building compact, high-frequency power converters for data center power supplies, EV onboard chargers, or industrial drives — buyers who need EMI compliance without sacrificing board density.
Who in Virginia should care
Defense electronics primes and suppliers clustered in Northern Virginia (e.g., supporting radar, power management for shipboard or airborne systems) would value compact, shielded magnetics for EMI-sensitive platforms.
Readiness: Concept
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
