Abstract

In one embodiment, the present invention includes an infrared apparatus to heat a body. The infrared apparatus includes layers. The first layer has a first conductive path coupled to pass a first current. The second layer has a second conductive path running coincident to the first conductive path. The second layer terminates an electric field produced within said first layer. The first conductive path includes a resistive element that produces heat from the current.
