An electrothermal deicing apparatus includes at least one heater conductor formed into a predetermined pattern for application to a structure. Each conductor of the pattern is coated with at least one layer of a material active to absorb electromagnetic energy. The pattern of the at least one coated heater conductor is operative to attenuate radar wave transmissions incident thereon to reduce the radar cross-section of the structure. A heater controller is coupled to the pattern of at least one coated heater conductor for controlling the deicing of the structure.
