Abstract

In this paper, a new topology optimization technique that incorporates design sensitivity and mutual energy concept is presented and applied to the inverse problem. The sensitivity in each design cell is calculated directly from potential distribution obtained from FEM (finite element method) simulation, and the material property in each cell is changed simultaneously using sensitivity information. The steepest-descent method is used as an optimization technique. The proposed method is applied to a numerical model whose permittivity of the design region is under consideration
