Abstract

In the automated design of magnetic devices using the optimized material distribution method, the material properties are allowed to vary continuously in each cell of the discretized design region. This leads to the appearance of intermediate materials whose properties do not correspond to an actual solid material. However, a correspondence can be made to composite materials, which are constructed from of a number of different solid materials. This approach permits accurate evaluation and stable optimization of the performance of a device. This paper derives the general composite microstructure of permeable intermediate materials
