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