If conventional inductor elements are miniaturized, then device size is reduced, but inductance value decreases
Solution Approach 1:
The patent changes the fundamental operating principle from conventional electromagnetic induction to quantum spin Hall effect, utilizing topological insulator materials with specific spin-orbit coupling properties. This parameter change enables inductance generation without traditional magnetic cores, achieving miniaturization while maintaining high inductance values through quantum mechanical effects rather than classical electromagnetic fields.
Solution Approach 2:
The patent replaces the mechanical/electromagnetic system of conventional inductors (winding coils, magnetic cores) with a quantum electronic system based on topological insulators and spin Hall effect. The inductance is generated through quantum mechanical spin-orbit coupling in the topological insulator material, substituting classical electromagnetic field generation with quantum electronic effects, thereby enabling significant size reduction.
