Optimization Method of Relativistic Backward Wave Oscillator Based on Multi-Level Deep Neural Network
摘要
Abstract
An optimization method of relativistic backward wave oscillator(RBWO)based on data-driven deep neural network is proposed.The structure or electrical parameters of RBWO are selected as the parameters to be optimized,and the corresponding working characteristic parameters under different parameters are generated by the fully electromagnetic particle-in-cell code,and the low-dimensional training data set and the high-dimensional training data set are generated.A multi-level deep neural network is developed,and the output of the low-level deep neural network is adopted as the input of the high-level deep neural network to realize the interconnection of the neural networks.Numerical examples show that the relative deviation between the predicted result of multi-level deep neural network and simulated results of fully electromagnetic particle simulation is less than 2%,indicating that they are in good agreement.This method addresses the challenge of achieving high prediction accuracy with limited sample data in deep neural networks,enabling high-precision optimization results.关键词
