Because of this, in addition to the common characteristics of ordinary radio waves, the microwave has its own characteristics, for example, microwave can go deep into the interior of certain materials and promote the interaction with their molecules or atoms, certain materials will cause thermal effects when absorbing microwave.
It almost penetrates glass, porcelain and other inorganic non-metallic materials without being absorbed.
Water, food, plastics, rubber and other organic materials will absorb it and be heated.
Metallic materials will reflect it.
Rubber and other organic materials have good absorbing properties, the input energy almost fully absorbs, so it can save more energy and get high energy efficiency
