| Summary | This paper proposes a new scheme for calculating the transient electromagnetic response in the time domain. It achieves efficient computation for large-scale underground models through the iterative solution of large sparse equation systems. A set of appropriate time steps and spatial grid discretization parameters are provided for commonly used step waveforms, enabling efficient computation for different models while meeting the requirements of computational error. Overall, this computational scheme has relatively low requirements for time steps and spatial grids, making it suitable for the wide and complex application scenarios of transient electromagnetic methods. |
