N2 - The ray tracing (RT) method and parabolic equation (PE) method are suitable for the solution of a large-scale electromagnetic propagation simulation in complex environment, but there are many disadvantages for both of these methods. The computation of the RT method dramatically increases in calculating the propagation of complex terrain, and PE method can only compute the complex electromagnetic (EM) propagation problem with a limited angle. In order to solve these problems, the hybrid algorithm is employed to compute the EM propagation in the three-dimension (3D) space with the 3DRT and quasi-3DPE methods. In the boundary of two methods, some overlapped parts are computed with the both methods to guarantee the efficiency of the results. Based on this hybrid method, two parallel modes, peer-to-peer mode and master/slave mode, are used to accelerate the computational process respectively. These two modes greatly increase the efficiency of the calculation process in different level with comparison of the serial computing method. Finally, the results of the calculation are performed for visualization.
