Perfectly Matched Layer (PML) has played a critical role in the development of Finite Difference Time Domain (FDTD) method, ever since it was proposed by Berenger in 1994. The formulation of PML has evolved from the original split-field PML approach to the time-convolution PML combining. The PML with the FDTD algorithm has enabled us to solve many engineering problems such as scattering, radiation, EMC and EMI. However, the FDTD method frequently suffers the later time instability when dealing with an irregularly shaped computational domain. In this communication, we investigate the stability characteristic of PML for extremely thin structures in the context of the parallel FDTD method.
