Abstract
A very large proportion of electromagnetic waves are reflected by the surface of the human body. To cope with this phenonmenon, the applicator of the present invention incorporates an electromagnetic lens at an electromagnetic wave-radiating end portion thereof, thereby enabling electromagnetic waves propagated in the human body to be gradually focused into a portion of the body to be heated. An omnidirectional electromagnetic lens is employed. Affected parts located at different depths in the body are generally treated by different applicators. However, the applicator of the present invention is constructed so that the electromagnetic lens is replacable. In consequence, only one case for the applicator is required. This makes the use of the applicator easier. For the purpose of providing a small-sized electromagnetic lens and applicator, coolant is made to flow inside the electromagnetic lens. This is effective from the viewpoint of the electromagnetic wave transmission system as well as with a view to tuning impedance of the human body.
