Rough Surface Models Implemented Within the Split-Step Parabolic Equation Algorithm

Applying the Parabolic Equation to Tropospheric Groundwave Propagation: A review of recent achievements and significant milestones

“…They combined PE with RT and other related technologies, utilizing their respective advantages to obtain improved simulation and prediction results. In the early 2000s, a relatively complete theoretical system was developed for PE problem solving, with such researchers as Craig [40], [41], Levy [1], [26], [42], Dockery [5], [6], [43], [44], Kuttler [11], [45]- [47], Barrios [48]- [50], and Hitney [39], [51], [52] making significant contributions. On the basis of this system, the United Kingdom and the United States developed a number of radio propagation prediction tools and software for engineering and military applications.…”
