Abstract

The invention discloses an efficient field-circuit co-simulation method based on a space mapping technology, and provides analysis on an energy selective surface based on a space mapping algorithm, the method mainly introduces a rough model and a fine model, the rough model with high calculation efficiency is used for solving in the solving process, and the calculation efficiency of the fine model is improved. And verifying by using a fine model with low calculation efficiency after solving is completed. According to the method, the rough model is an equivalent circuit model, the fine model is a real physical model, and the result shows that the method not only can keep high accuracy, but also has a remarkable acceleration effect.

Description

technical field [0001] The invention belongs to the field of efficient analysis of the coupling problem between circuits and electromagnetic fields, in particular to a numerical analysis method designed for the coupling problem of nonlinear circuits and electromagnetic fields, in particular to an efficient field-circuit co-simulation method based on space mapping technology. Background technique [0002] The spatial mapping algorithm is an optimization algorithm proposed by Canadian scholars Bandler.J.W and Biernacki.R.M in 1994. The algorithm involves a coarse model and a fine model. The core idea is: Assuming that there is a certain mapping relationship between the coarse model and the fine model, using this mapping relationship, the optimization of the complex and time-consuming fine model can be transformed into a simple and fast model. The optimization of the rough model, so as to achieve the purpose of efficient optimization. Common spatial mapping algorithms include:...
