| Abstract(in English) | A surrogate-based electromagnetic (EM) optimization method using neural networks (NNs) is presented for computationally efficient microwave bandpass filter (BPF) design. This paper first describes the forward problem (EM analysis) and the inverse problems (EM circuit design), and the two fundamental issues in BPF designs. To accelerate the BPF design, two surrogate models of forward and inverse models are introduced, which are built with NNs. As a result, the inverse model can instantaneously guess initial structural parameters with high accuracy by inputting synthesized coupling-matrix elements into the NN. Then, the forward model in conjunction with optimization algorithm enables designers to rapidly find optimal structural parameters. The effectiveness of the surrogate-based EM optimization is verified through structural designs of a fifth-order microstrip BPF. |
