Numerical solution of the parabolic equation representing electromagnetic wave propagation in the troposphere using the box method

摘要

Abstract: An implicit finite - difference (IFD) scheme is introduced for solving the parabolic equation representing electromagnetic wave propagation in the troposphere. Using Box method, the fading to the electromagnetic wave is calculated especially when the modified refractivity varies both with the range and the height in the representative atmosphere conditions. The consistency, stability and convergence of the Box method is demonstrated.!11
