摘要：
Efficient, accurate and unconditionally stable perfectly matched layer (PML) formulations are presented for truncating Finite Difference Time Domain grids. The formulations are based on incorporating the Crank-Nicolson scheme into the modified Helmholtz wave-equation derived in the PML re-ion. Numerical example carried out in onedimension is included to validate the proposed formulations.
