Abstract
A wind turbine with reduced electromagnetic scattering includes a wind turbine support structure having a cylindrical shape, a wind turbine blade supported by the wind support structure, and a plurality of multi-layer absorbers to limit the electromagnetic scattering, the absorber including at least cobalt ferrite alloy nano-particles, cobalt ferrite alloy nano-flakes, and air. The wind turbine blade includes a blade root, a blade tip opposite the blade root, and a blade middle part extending between the blade root and the blade tip. The plurality of multi-layer absorbers further includes a planar absorber that covers the wind turbine support structure, and a curved absorber that covers the middle part.
