Well-Designed Termination Wall of Perfectly Matched Layers for ATS-FDTD Method

الملخص EN

This paper presents a well-designed termination wall for the perfectly matched layers (PML).

This termination wall is derived from Mur’s absorbing boundary condition (ABC) with special difference schemes.

Numerical experiments illustrate that PML and the termination wall works well with ATS-FDTD(Shi et al.

2015).

With the help of termination wall, perfectly matched layers can be decreased to two layers only; meanwhile, the reflection error still reaches -60[dB] when complex waveguide is simulated by ATS-FDTD.
