Abstract

The development of a millimeter and submillimeter wave catheter for irradiation of the tissues of living bodies is described. The power sources of electromagnetic waves are an impatt oscillator and a gyrotron. A Teflon rod dielectric antenna or a newly designed waveguide vent antenna with a dielectric sheet is used as a launcher for the irradiation. Preliminary measurements on the denaturalization of tissue are performed.
