to whom it may concern: sorry to trouble you. I am a PhD student in Ocean University of China. My major is geophysics and research topic is controlled-source marine electromagnetic (CSEM) modeling and inversion. my research interests focus on the electromagnetic numerical simulations. I try to apply the DG method to my research based on your software Nnetar++ platform. The DG method is usually used to time-domain electromagnetic in the papers published. Does the DG method suitable to the frequency-domain electromagnetic problem and is there perfect theory about the DG method in electromagnetic simulation until now ? And does this method suitable to the low frequency electromagnetic (0.01Hz~10Hz) simulation ? Looking forward to your reply. Thank your so much for your time and have a nice day. Best wishes, Jiankai Li
