Enhanced electromagnetic scattering analysis of wind turbine structures using the method of auxiliary sources (MAS): a high-resolution study

The rapid expansion of wind energy systems has necessitated detailed studies of their electromagnetic interactions, particularly concerning compatibility with nearby communication and radar systems. This study employs the Method of Auxiliary Sources (MAS), a computationally efficient and highly accurate approach, to investigate the electromagnetic scattering effects of wind turbine wings. Numerical simulations were conducted for various frequencies and incident angles, revealing critical insights into diffraction, shadowing, and standing wave formations. Comparative analyses with established methods, including FEKO, demonstrate that MAS achieves superior accuracy with significantly lower computational demands. The results can be used for the design of wind turbine structures and their placement to minimize electromagnetic interference (EMI) with communication systems. This study highlights MAS as a transformative tool for advancing electromagnetic compatibility research in renewable energy systems.
