Authors

This new approach enhances stability in ground penetrating radar modeling, ensuring accurate results with larger time steps.

The proposed method improves stability in GPR modeling by eliminating eigenmodes of the coefficient matrix, enhancing reliability.
Using a relatively large time step, the technique overcomes limitations imposed by the CFL stability condition, boosting efficiency.
Comparative analysis of the new method against conventional FDTD shows significant improvements in accuracy and speed.
The explicit unconditionally stable technique is particularly effective for simulating TM wave backscattering in lossy media.

Zhang et al. (2025) studied this question.
