1. A de-icing system for an aircraft comprising:
- a flexible substrate incorporating a matrix of a plurality of resistive-inductive heating elements adapted to be carried by a flight control surface;
said matrix configuration of the plurality of resistive-inductive heating elements including an m×
n matrix with the m resistive-inductive heating elements connected in series and the n resistive-inductive heating elements in parallel;
said matrix configuration of the plurality of resistive-inductive heating elements being arranged such that adjacent resistive-inductive heating elements have opposite magnetic polarity;
a controller configured to provide a supply current to each of the plurality of resistive-inductive heating elements, wherein the controller may receive current from a plurality of current sources;
wherein each of the plurality of resistive-inductive heating elements produces an electromagnetic field and resistive heat in response to the supply current and wherein the electromagnetic field normal to the flight control surfaces induces an eddy current in the flight control surface;
and wherein the electromagnetic field produced by each of the plurality of resistive-inductive heating elements is strong enough to totally penetrate the flight control surface.

Abstract
Embodiments of the disclosure include a de-icing system for an aircraft. The de-icing system includes a plurality of resistive-inductive heating elements inserted adjacent to a flight control surface and a controller configured to provide a supply current to each of the plurality of resistive-inductive heating elements. Each of the plurality of resistive-inductive heating elements produces an electromagnetic field normal to the flight control surfaces and resistive heat in response to the supply current. The electromagnetic field induces an eddy current in the flight control surface.
