Radiowave heating is a method that uses electromagnetic waves, specifically in the radio frequency range, to generate heat in materials. This technique is commonly used in industrial applications, such as drying and curing processes, where it efficiently heats products without direct contact. The process works by causing polar molecules within the material to vibrate, which generates heat. Radiowave heating is also utilized in some cooking appliances, like microwave ovens, where it cooks food quickly and evenly. This technology is valued for its speed and energy efficiency compared to traditional heating methods.
