✦ Synopsis

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 that a simple LTBC can be effecti¨ely used to account for the radiation in TDP, instead of the recently published ( ) nonlocal transparent boundary condition NTBC , which is much more complex and consumes more computer time.
