A device known as a radio frequency heating system, or simply RF heating, uses electromagnetic waves in the radio frequency spectrum to heat or cook a variety of materials. RF heating, in contrast to conventional heating techniques, which rely on conduction or convection, uses high-frequency electromagnetic fields to produce heat inside the material being processed. By exposing the material to an RF generator, which produces electromagnetic waves at a specified frequency, this is accomplished. The material’s molecules quickly oscillate as a result of the waves’ interaction with them, creating heat as a result of the friction between the molecules.
