Abstract
The present disclosure discloses a negative inductor device. The negative inductor device comprises a negative inductor comprising a ferromagnetic material and a conductive material arranged inside the ferromagnetic material. The negative inductor device further comprises a current limiting circuit electrically coupled to the negative inductor and configured to supply an electric current of magnitude within a range, the range being defined by a first local minimum and a second local minimum of a current-energy curve of the ferromagnetic material.
Claims15
A negative inductor device, comprising:
- a negative inductor comprising a ferromagnetic material and a conductive material arranged inside the ferromagnetic material;
- and
- a current limiting circuit electrically coupled to the negative inductor and configured to supply an electric current of magnitude within a range, the range defined by a first local minimum and a second local minimum of a current-energy curve of the ferromagnetic material.
A negative inductor, comprising:
- a ferromagnetic material;
- and
- a conductive material partly enclosed in the ferromagnetic material such that opposite ends of the conductive material are protruded from the ferromagnetic material, wherein the opposite ends of the conductive material that are protruded from the ferromagnetic material correspond to terminals of the negative inductor.
A negative inductor, comprising:
- a ferromagnetic material;
- and
- a conductive material arranged inside the ferromagnetic material.
A fabrication method for a negative inductor, the fabrication method comprising:
- depositing a first layer of a ferromagnetic material on a substrate;
- forming a metal spiral on a surface of the first layer of the ferromagnetic material;
- and
- depositing a second layer of the ferromagnetic material on the first layer of ferromagnetic material, and the metal spiral.
