%X An implicit finite-difference (IFD) scheme of box method is introduced for solving the parabolic equation representing electromagnetic wave propagation in the troposphere. The consistency, stability and convergence of the box method is demonstrated. More accurate results are obtained while the modified refrac-tivity varies both with the height and the distance. Compared with the popular used Fourier split-step method, the box method has the advantage of having more accurate results and solving boundary conditions easier.
