Abstract

An electromagnetic applicator for use in hyperthermic treatments of superficial and subcutaneous tissues employing radiators integrated in a waveguide segment which is working below the cutoff frequency and supports evanscent modes of propagation which are excited by the radiators to produce a multi-modal field of controlled intensity. Additional radiators are integrated in the same waveguide to generate directly another controlled field. The multi-modal and directly emitted field are generated with a large variety of field sizes, shapes and penetration features and are combined in many ways and in any power level ratio to provide a heating field emerging from the waveguide aperture which impinges upon tissue to be heated through a noncritical air gap thereby allowing heating of a large variety of subcutaneous tumors to temperatures causing tumor necrosis without injury to the normal fat and other access tissues. Moreover, palliative treatments may be performed on subcutaneous muscle tissues and joints and on hypertrophic tissues.
