For example, induction coils powered by an electrical supply generate high frequency electromagnetic fîelds which are absorbed by a layer of a smart suscepting alloy. The fîelds are transformed into eddy currents on a surface including the smart suscepting alloy, with the current generating heat via ohmic losses to provide de-icing. Along with acceptable efficiency, various embodiments do not require direct contact between an induction coil and a heated surface.


A heating surface (e.g., a heating surface including a smart susceptible alloy as discussed herein) is more robust than a heating wire, for example because the surface will still provide heat even if a portion of the surface is damaged. In contrast, a heating wire, if damaged at one point, may not continue to provide heat.

In the illustrated embodiment, the anti-icing heating surface 114 includes a smart suscepting alloy 115. A smart suscepting alloy as used herein may be understood to include alloys that hâve magnetic susceptibility between 10 and 10,000, and which lose magnetic susceptibility when a température approaches a spécifie Curie température, thereby helping to limit a maximum température to which the smart suscepting alloy 115 (and anti-icing heating surface 114) may be heated.
