“…Since not restricted within paraxial region, TDWP seems to have more potential than SSPE in modeling propagation problems. Terrain effects and surface roughness as well as ground losses [24][25] can be modeled, where any kind of transverse and/or longitudinal refractivity profiles can be taken into account [26,27]. The technique may also be applied to vertical propagation [28] or any other waveguiding structures [29].…”

“…Due to the ability of FD-and FE-based numerical schemes to model different kind of boundaries, the TBCs have been developed for PE solutions based on those schemes. The rigorous treatment of the radiation boundary condition problem leads to non-local TBCs (NTBCs) [33,59,82]. The NTBC for narrow-angle PE has been proposed and successfully applied to the microwave tropospheric propagation under ducting conditions in Levy [83] using a FD-based numerical scheme; for a wide-angle NTBC the reader is referred to Zebic-Le Hyaric [84].…”

This work provides an introduction to one of the most widely used advanced methods for wave propagation modeling, the Parabolic Equation (PE) method, with emphasis on its application to tropospheric radio propagation in coastal and maritime regions. The assumptions of the derivation, the advantages and drawbacks of the PE, the numerical methods for solving it, and the boundary and initial conditions for its application to the tropospheric propagation problem are briefly discussed. More details are given for the split-step Fourier-transform (SSF) solution of the PE. The environmental input to the PE, the methods for tropospheric refractivity profiling, their accuracy, limitations, and the average refractivity modeling are also summarized. The reported results illustrate the application of finite element (FE) based and SSF-based solutions of the PE for one of the most difficult to treat propagation mechanisms, yet of great significance for the performance of radars and communications links working in coastal and maritime zones -the tropospheric ducting mechanism. Recent achievements, some unresolved issues and ongoing developments related to further improvements of the PE method application to the propagation channel modeling in sea environment are highlighted.

An efficient numerical scheme to simulate tropospheric ducting propagation (TDP) is presented in this paper. This scheme solves the parabolic equation (PE) approximation in conjunction with the finite‐element method (FEM) and the local transparent boundary condition (LTBC). It is shown that a simple LTBC can be effectively used to account for the radiation in TDP, instead of the recently published nonlocal transparent boundary condition (NTBC), which is much more complex and consumes more computer time. ©1999 John Wiley & Sons, Inc.
