Abstract

Unconditionally stable formulations of the perfectly matched layer (PML) are presented for truncating linear dispersive finite‐difference time‐domain (FDTD) grids. In the proposed formulations, the 𝒵‐transform theory is employed in the alternating‐direction implicit FDTD (ADI‐FDTD) algorithm to obtain update equations for the field components in dispersive media. The validity of the proposed formulations is shown through a numerical example carried out in 1D linear Lorentz dispersive FDTD domain. © 2005 Wiley Periodicals, Inc.

A new unconditionally stable algorithm for steady-state fluid simulation of high density plasma discharge is suggested. The physical origin of restriction on simulation time step is discussed and a new method to overcome it is explained. To compare the new method with previous other methods, a one-d
