“…With the rapid development of computer field, computer aided design (CAD) technology has been greatly improved, and it is also used for simulation design of electromagnetic problems [1], generally using full-wave electromagnetic simulation software including high frequency structural simulator (HFSS), Computer Simulation Technology (CST), etc. When optimizing the electromagnetic problems, global optimization algorithms, such as particle swarm optimization (PSO) [2], [3], [4], [5], genetic algorithm (GA) [6], [7], [8] ant colony optimization (ACO) [9], [10], [11] etc., are usually used in combination with electromagnetic simulation software. However, this process repeatedly calls electromagnetic simulation software for electromagnetic performance evaluation, which is very time-consuming.…”
