Abstract :
The microwave invasion into living bodies at a millimeter wave catheter irradiation is described. The power sources of millimeter wave are an Impatt oscillator (94 GHz, 0.3 W) for the irradiation tests, a Gunn oscillator (90 GHz, 13 mW) for the reflection study, and a gyrotron for high power irradiation. Irradiated samples are cow livers and living rats. In the newly designed irradiation antennas, a part of the copper waveguide is replaced with the flexible Teflon rod.
