Wave Propagation Modelling - Urban environment

Wave Propagation Modelling - Urban
Our group have expertise in propagation modelling in urban environments for mobile radio applications. We have developed asymptotic models based on 2D and 3D ray tracing, and are currently working on developing full-wave models based on the surface integral equation formulation. These have currently been applied to 2D propagation in the vertical plane (rooftop diffraction) and implicitly account for all multiple scattering effects along the profile.
A block forward backward method is used to iterate the solutions, efficiently capturing the wave interactions along the profile. Advanced mathematical acceleration techniques such as the Fast Far Field Algorithm (FAFFA) and others based on the FFT reduce the associated computational burden so that these highly accurate solutions can be computed in realistic time-frames on a seconds on a standard desktop machine.
