Research Summary

I participated in this research program led by Pan Zhang from China University of Petroleum under the supervision of Prof. Jiefu Chen, Xuqing Wu and Shaogui Deng.

We have adopted the PINN strategy and apply it to time-domain electromagnetic simulations based on Maxwell’s equations. Compared to the existing PINN methods which are based on one variable PDE, our scheme is to solve both electric and magnetic fields simultaneously. Moreover, we will take media inhomogeneity and interface conditions into account in the loss function, while the previous PINN papers did not discuss these important issues. In the section of numerical examples, we will compare our network-based method with conventional FDTD to test the feasibility and accuracy of our work.
