WebbThe microwave range shows relevant advantages with respect to other frequencies in open-air transmission, such as low absorption losses and … Webb15 juni 2024 · A material with good microwave absorption rapidly absorbs microwave energy. Thus, as the size increases, the microwaves do not heat the interior but heats only the surface. Conversely, in a material with moderate microwave absorption properties, microwaves can penetrate further into the interior.
