摘要
This letter presents a derivation of the closed-form expression of numerical reflection at interfaces of perfectly matched layer (PML), Reflection coefficients at single interfaces and of finite-thickness absorbers are presented, The derived closed-form expression is found to match identically with the refection coefficient obtained directly through finite-difference time-domain computation, The closed-form expression of numerical reflection coefficient can significantly facilitate the optimization of PML performance.
