Scatter electromagnetic waves by rotating. As a result, the electromagnetic waves are those that directly hit the object to be heated (7) and those that hit the heated object (7) once.
1) and then the object to be heated (7), and the electromagnetic waves repeatedly impinge on the object to be heated (7) from various directions. When the object to be heated (7) is struck and penetrated by electromagnetic waves, its constituent molecules vibrate, generating frictional heat, and the temperature rises due to so-called dielectric heating.
