| Outline of Final Research Achievements |
An effective numerical technique for calculating the eigen frequencies by means of the block SS method and the boundary element method (BEM). Next, for two-dimensional electromagnetic field, a BEM has been formulated. A typical objective functional has been defined and the rigorous mathematical expression of the topological derivative of the objective functional has been derived. It has been used for the topology optimization procedure based on the level set method. The effectiveness of the present approach has been demonstrated through numerical experiments. For a more general three-dimensional problems, a BEM for solving Maxwell’s equations has also been derived. For an objective functional appropriately defined, the topological derivative for emergence of an infinitesimal scatterer has been derived and applied to the topology optimization of calculating the optimum distribution of the scatterers.
