Abstract

The development of a millimeter- and submillimeter-wave catheter for irradiation on living bodies using a Teflon rod dielectric antenna is described. The power sources of electromagnetic wave are an Impatt oscillator (90 GHz, 0.3 W) and a gyrotron (302 GHz, 30 W). Irradiation tests using various Teflon rod dielectric antennas were performed on cow livers, living rats and a cancerous tumor implanted in living mice. Irradiation results were considered by microwave theory and ray optics.
