RF Applications

Many different types of materials may be heated by exposure to a high-frequency electric field. Nonmetallic or non-conducting materials that are difficult to heat uniformly by conventional heating methods are particularly suitable for high-frequency heating, providing they possess the necessary physical, chemical and electrical properties.
