Marching-on-in-degree time-domain integral equation solver with high-level basis functions for transient electromagnetic scattering

In this paper, the transient electromagnetic scattering of the benchmark target, i.e. the NASA almond, is calculated utilizing the marching-on-in-degree time-domain integral equation method with high-level spatial and temporal basis functions. Much memory requirement reduction and unconditionally stable solution in late time can be ensured. The time-domain solution is then Fourier transformed, and wide frequency band information is obtained. As a further discussion of the previous work of the authors, numerical results of the NASA almond are provided and discussed.
