Electromagnetic Scattering from Cylinders: A Single-Scattering Model

As a new generation of wireless communications approaches, there is an increasing emphasis on leveraging the characteristics of urban wireless channels to facilitate higher data rates and improved connection quality. Modeling the propagation environment emerges as a crucial factor to ensure optimized network performance and reliable connectivity for users. State-of-the-art electromagnetic modelling techniques employ ray-tracing algorithms and scattering models of urban furniture to improve the accuracy of the computed path gain. In this context, cylinders stand out as one of the most common 3D shapes present in urban environments. This work presents a scattering model for metallic cylinders that is based on Fresnel integrals and addresses some of the most notable issues that existing scattering models suffer from, mainly computational complexity and near-field validity. The model is applied to a single-scattering scenario and its accuracy is showcased with respect to the results of measurements performed in an anechoic chamber.
