Abstract
In this paper, the derivation of three asymptotic boundary conditions is presented. Techniques for implementing each of these on finite diff erence meshes with rectangular outer boundaries are discussed. Numeric al results obtained using these boundary conditions in the finite diff erence analysis of both shielded and unshielded transmission lines are shown. We present detailed convergence studies on the use of each of these boundary conditions and discuss the memory requirements of each.
