提出了一种基于时域有限差分技术和拓扑优化的优化设计方法。拓扑优化是一种通过调整设计空间的材料特性来搜索最优形状的方案。通过引入伴随变量法，可以有效地估计目标函数对设计变量的导数。为了验证我们的方法，在TM/sup Z/案例中测试了一个介电结构的形状设计问题。在本例中，每个栅格处的介电常数密度作为设计变量。
In this paper, an optimal design method based on the FDTD technique and the topology optimization is proposed. Topology Optimization is a scheme to search an optimal shape by adjusting the material properties of design space. And by introducing the adjoint variable method, we can effectively estimate a derivative of objective function with respect to design variable. In order to verify our method, a shape design problem of dielectric structure is tested in the TM/sup Z/ case. In this example, the permittivity density at each grid is taken as design variable.
