Efficient Explicit Finite‐Difference Frequency‐Domain for Large‐Scale 3D Problems
Haolin Li, Shuo Liu, Linlin WangABSTRACT
In this paper, an efficient explicit finite‐difference frequency‐domain (E‐FDFD) method is proposed for full‐wave analysis of electrically large structures in the microwave frequency bands. The proposed method avoids solving large matrix systems by calculating the electromagnetic field iteratively along a specific spatial axis, significantly reducing both computational time and memory requirements. Some numerical experiments are given and experimental results show that the proposed E‐FDFD scheme outperforms conventional frequency‐domain methods in terms of efficiency, making it a promising technique for scattering analysis of electrically‐large objects.
