用三维抛物方程的CNFD技术计算传播损耗
The CNFD Technique of 3D Parabolic Equation for Calculating Propagation Loss
摘要
Abstract
A three dimensional parabolic equation(3DPE)method is applied to predict the propagation loss of radio wave. Firstly, the three dimensional parabolic equation is derived. Secondly, the technique of CNFD together with the traditional nonlocal absorbing boundary condition is adopted. In addition, the preconditioned matrix technique is used to handle the large scale matrix equation. Finally, numerical results between the parabolic equation method and two ray theory agree very well.关键词
