The perfectly matched layer (PML) boundary condition for the scalar FDTD is implemented and verified by the simulation for the parallel slab directional coupler.

The perfectly matched layer (PML) absorbing boundary condition is used in the FDTD analysis of planar optical waveguide structures.

Discontinuities in waveguides are analyzed by the finite-difference time-domain (FDTD) method with perfectly matched layer (PML) absorbing boundary condition (ABC).

Absorbing performance of one-dimensional perfectly matched layers (PML) isanalyzed and its theoretical reflection coefficientis presented in consideration of the influence of thefinite-difference approximation in this paper.

The interior region,treated using the FEM,is truncated to a single periodic unit cell;the combination of PML,periodic boundary and incident boundary extraordinarily simplified the calculation of the open space problems.

This paper presents a new scheme,which is used in discretizing Berenger s split field representation of Maxwell s equations,in order to use the perfectly matched layer(PML) with the alternating direction implicit(ADI) finite-difference time-domain(FDTD) method instead of the standard FDTD method.

As an efficient artificial truncating boundary condition, conformal perfectly matched layer (CPML) is a kind of multilayer anisotropic absorbing media.

Based on five states that would arise in the matching of labor and capital in economy,the paper analyzes the ideal matching term of capital and labor under the condition of manufacturers in the environment of competition and then analyzes influence on collocation of investment factors that would come into being because of the gap of real and ideal matching of capital and labor in economy.
