With the variety of different radiators, the microwave treatment offers a diverse field of applications. The produced heat can be reduced by increasing the distance between the radiator and the treatment site.

The microwave radiation can be focused and is therefore excellently applicable for treating locally specific body parts. Thus, it is particularly suitable for the otolaryngology, dental and orthodontic medicine. For these fields microwave is preferred over shortwave.

Within the body, microwaves execute thermal (i.e. heat) and extrathermal (i.e. vibration) physico-chemical processes.
