Research Projects

Microfabricated magnetic components using nanomaterials

Microfabricated magnetic components using nanomaterials

Microfabricated magnetic components using nanomaterials make it possible to miniaturize power-handling magnetic components through taking advantage of the materials' high-flux-density and high-frequency capabilities. We are developing practical methods of depositing these materials and fabricating inductors and transformers on silicon chips or in other technologies.
Passive high-frequency power components

Passive high-frequency power components

Passive high-frequency power components are often the limiting factors in reducing the power loss, size, cost, and weight of high-frequency electronic power converters. Through detailed analysis, modeling, and optimization of high-frequency effects in inductors, transformers, and capacitors, we are improving performance of these components and making it easier to design the efficient, low-cost power electronics needed for a wide range of applications including energy efficiency and renewable energy.
