Report Summary: Topology optimization can simultaneously change the number and shape of holes in the structure to be optimized, and simultaneously optimize its connectivity, providing greater design freedom. Therefore, topology optimization can better realize the performance optimization of the structure. Due to the large number of variables to be optimized, the traditional direct optimization method will lead to long convergence time. Fast topology optimization can be achieved by using gradient information, i.e., sensitivity analysis. Our research group has improved the topology optimization method based on sensitivity analysis, and proposed several optimization methods that contribute to the realization of high-performance electromagnetic structures, and applied them to the optimization of electromagnetic structures such as antennas.
