Microwave interacts with material molecules in a rapidly changing high-frequency electromagnetic field and is absorbed to produce a thermal effect, directly converting microwave energy into thermal energy in the medium. After the microwave is absorbed by the object, the object generates heat automatically. Heating starts from the inside and outside of the object at the same time, enabling simultaneous heating inside and outside. Different materials have different abilities to absorb microwave, and their heating effects vary, which mainly depends on the dielectric loss of the material. Water is a substance that strongly absorbs microwaves. Generally, substances containing water can be heated with microwaves, quickly and evenly, achieving good results.
