Recently, surrogate models using deep learning are introduced to speed up electromagnetic (EM) analysis. For instance, a surrogate model, of which the input is image of geometry under analysis and the output is its characteristics, has been constructed by convolutional neural network. However, a large amount of EM analysis results is required to build such surrogate models. To solve this problem, this paper proposes a novel surrogate model consisting of an encoder and fully connected layers for an extremely fast calculation of frequency response of planar BPFs (bandpass filters). In the proposed surrogate model, the amount of data prepared using EM analysis can be reduced by a pre-generated encoder that can extract features of geometry of BPFs from their images. As an example, we construct the surrogate model for third-order planar BPF by using convolutional autoencoder and transfer learning. The generalization performance of the surrogate model is evaluated by comparing the calculation accuracy of frequency responses between the proposed and conventional approaches. |
