Simultaneous Optimization of Material Selection and Structure for Antenna Design using Differential Evolution Algorithm

Simultaneous optimization of material selection and structure is important for antennas, but it remains a difficult problem. To maintain the simplicity in structure, an adaptive discrete variable selection approach is proposed for the differential evolution algorithm to optimize the design problems with mixed variables effectively. For demonstration, the adaptive discrete variable selection based differential evolution algorithm (ADVSDE) was adopted to optimize a practical design problems. The results show that the proposed algorithm can effectively optimize the material selection and structure parameters, which cannot be handled by the existing optimization algorithms.
