1. A wind turbine comprising: a plurality of elements including a tower, a nacelle mounted to the tower and a plurality of blades rotatable mounted to the nacelle, wherein at least one element of the tower, the nacelle, and the plurality of blades is configured to exhibit electromagnetic oscillation along an axis of the at least one element with a resonance frequency (fn) of an order n, and comprises a coaxial impedance member that is coaxially arranged about the axis of the at least one element, and is tuned to the resonance frequency of the order n.
