Abstract :
Nonlinear time-domain numerical modeling requires the development of absorbing boundary conditions to effectively absorb the nonlinear electromagnetic waves. In this paper, based on Berenger´s PML (1994), the nonlinear perfectly matched layer (nPML) absorbing condition is developed and implemented in the recently proposed TLM-based FDTD method. Numerical results show the effectiveness of the nPML. The proposed nPML scheme can also be implemented in other FDTD schemes.
