摘要：

We examine three simply implemented boundary conditions for finite-difference electric field propagation. We find that although so-called transparent boundary conditions are appropriate for highly collimated beams, properly tailored absorbers are generally better adapted to realistic field distributions. Our analysis incorporates a simple procedure for constructing nearly optimal absorber functions as well as a novel mixed transparent/absorbing boundary condition.
