Various tissues, cells, body fluids and the like contained in a living body are not composed of a large number of molecules and ions. Molecules can be divided into polar molecules and nonpolar molecules, wherein the centers of positive and negative charges in the interior of the molecules are separated, and the centers of positive and negative charges in the interior of the molecules are overlapped. The ions are molecules or groups of molecules, atoms or groups of atoms lose or get electrons to become charged positive ions or negative ions. When electromagnetic waves act on biological tissues, the electromagnetic waves are subjected to the action of an external electromagnetic field, and the following two mechanisms of thermal effects occur.

Ohmic heating effect: the free electrons and ions in the biological tissue move along the direction of the applied electric field and magnetic field to act on the biological tissue, so that directional conduction current or local vortex current is caused, and the current interacts with the electrical impedance of the biological tissue to generate ohmic heating effect.

Wave energy heating effect: the polar molecules vibrate with the frequency under the action of the alternating electromagnetic field, the original nonpolar molecules become polarized molecules due to the action of the electromagnetic field, and the polarized molecules vibrate with the frequency of the electromagnetic field, so that the internal energy of the molecules is increased, namely the wave energy heating effect is generated. Both the directional or swirling motion of electrons, ions, and the high frequency vibration of polarized molecules, the friction between ions, the friction between polarized molecules, and the mutual friction between ions and polarized molecules are all aggravated, and these friction can generate thermal effects.

In the first case, a strong current flows in the living body, and the low-frequency electromagnetic wave is mainly an ohmic heating effect for the living body; in the second case, the current flowing in the living body is weak, and the high-frequency vibration of the polar molecules tends to be dominant by the high-frequency electromagnetic field, and the wave energy heating effect is dominant. Regardless of the effect of heating, this is manifested by absorption of electromagnetic wave energy by the biological tissue and conversion of electromagnetic wave energy into thermal energy, causing the temperature of the biological tissue to rise.

The main mechanism of heating tissue medium by radio frequency electric field is as follows: firstly, a large number of polar molecules (H2O and the like) exist in human tissues, and the polar molecules rotate rapidly along with the change of the electric field size and the direction in a high-frequency electric field, and vibration and the like cause friction and collision among molecules to generate a large amount of heat; secondly, under the effect of the radio frequency electric field, positive and negative charges in some originally electrically neutral molecules in the tissue medium are repeatedly pulled and polarized at high speed, and the electric field energy is converted into heat energy. It is also not equal to the radio frequency current of the cable connected to the plate. The rf electric field is therefore considered to be primarily polarized current heating.
