Automated Topology Design for Electromagnetic Devices

چکیده
In this paper a novel automated design procedure based on the integration of a full wave Finite Element Analysis (FEA) and a topology design method employing Sequential Linear Programming (SLP) is introduced. The employed topology design method is the Solid Isotropic Material with Penalization (SIMP) technique which is formulated as a general non-linear optimization problem. SLP is used to solve the optimization problem with the sensitivity analysis based on the adjoint variable method for complex variables. A key aspect of the proposed design method is the integration of optimization tools with a fast simulator based on the Finite Element-Boundary Integral (FEBI) method. The capability of the proposed design method is demonstrated by designing a patch antenna subject to prespecified bandwidth and miniaturization criteria. Results show that the proposed design method is capable of designing full three-dimensional volumetric material textures and printed conductor topologies for filters and patch antennas with enhanced performance.
