Efficient Fresnel Diffraction for Wind Turbines

Wind turbines (WTs) are a growing source of renewable energy. However, a WT bears adverse effects on different telecommunication systems due to its complex interaction with electromagnetic waves. To model the diffraction effects of such complex shapes, methods based on ray tracing and numerical integration over obstacle apertures have been developed but they are typically computationally involved.In this work, the diffraction loss of a WT is obtained with a computationally efficient method that allows to model different rotations of the blades, and the nacelle (i.e. the yaw angle).
