摘要：
This paper proposes a multiple level set method for multi-material shape optimization in an electromagnetic system. This method enables the handling of multi-material interfaces simultaneously. The sign combination of the level set functions is used for identifying the different material regions and their interfaces. The continuum sensitivity formula for the multi-material interfaces is adopted for the velocity field in the multiple level set equations. Numerical examples are tested to show the usefulness of the proposed method.
