Radar absorbing material compatible with lightning protection systems |
| abstract |
A wind turbine component incorporating radar-absorbing material having increased compatibility with lightning protection systems is described. The radar absorbing material includes a ground plane having an electrical conductivity and/or a dielectric constant that is higher in the presence of an electric field having a frequency of 1 GHz and above than in the presence of an electric field having a frequency of 10 MHz and below. Suitable materials for the ground plane include ferroelectric and ferrimagnetic materials and percolating material combinations, all of which have frequency-dependent properties that can be tuned to make the ground plane highly reflective at radar frequencies and benign at lightning discharge frequencies. |
