An efficient numerical scheme to simulate tropospheric ( ) ducting propagation TDP is presented in this paper. This scheme sol¨es ( ) the parabolic equation PE approximation in conjunction with the ( ) finite-element method FEM and the local transparent boundary condi-( ) tion LTBC . It is shown tha
The perfectly matched layer boundary condition is incorporated into the beam propagation method based on a "nite element scheme for 3-D optical waveguides. Not only an approximate scalar formulation but a full-wave formulation is presented. Its e!ectiveness is veri"ed by way of numerical examples.
