Abstract :
This paper presents a design method for coreless inductors based on admittance matrix, at quasi-static approximation, and an optimization technique based on continuum sensitivity. We show the efficiency of the design method for inductors that have 2D symmetry, in axial plane. In order to avoid coupling between closely located inductors, a conductive shielding structure is proposed and shape-optimized to reduce the mutual coupling
