Wave Propagation Modelling - Rural terrain

Wave Propagation Modelling - Rural Terrain
Our group have developed a number of novel path loss models for propagation over rural terrain profiles. The models are based on the surface integral equation formulation and are full-wave. This means that they implicitly account for all multiple scattering effects along the profile and offer greatly improved accuracy over knife-edge diffraction models.
Advanced mathematical compression and acceleration techniques such as the Fast Far Field Algorithm (FAFFA) and Improved Tabulated Interaction Method (I-TIM) reduce the associated computational burden so that these highly accurate solutions can be computed in seconds on a standard desktop machine (in contrast to unaccelerated solutions which would take several hours to run, depending on frequency).
