Improving Propagation Channels With Static Scatterers

This letter explores the potential enhancement of radio signal propagation in intricate environments through the deployment of basic resonant dipole scatterers. We employ the MATLAB ray tracer algorithm to examine the impact of dipolar scatterers on the power received at the user's location. The ray tracing model is modified for a dipolar scatterer model based on its bi-static scattering cross-section. Our analytical and simulation results indicate that the deployment of extra scattering components is nearly ineffective when a direct link is present. Conversely, in scenarios where there is no line-of-sight, the proposed approach can considerably boost the power delivered. This cost-effective and straightforward method could complement other channel optimization strategies, such as the application of reconfigurable intelligent surfaces.
