Abstract
A medium formed by a mixture of polymeric binder with conductive metal and either semiconductive particles or galvanic couple alloy particles that can be coated or printed on a substrate to convert electromagnetic radiation to heat without arcing and produce increase heating of foods. Conversion efficiency can be controlled by the choice, thickness, pattern and amount of materials used in the medium. The medium can be formulated to be used repeatedly without burn out or can be formulated to be used only once after which it becomes microwave inert. The conductive particles are typically aluminum, copper, zinc and nickel; the semiconductive particles are typically carbon, titanium carbide, silicon carbide and zinc oxide; and the galvanic couple alloy particles are typically aluminum-nickel alloy, aluminum-cobalt alloy and aluminum-copper alloy.
