Abstract :
The microwave invasion to living bodies at a millimeter wave catheter irradiation is described. The power sources of millimeter wave are an IMPATT oscillator (IO) for the irradiation tests and a Gunn oscillator for the reflection study. Irradiated samples are cow livers and living rats. A newly designed wave-guide vent antenna (WVA) with an anti-reflecting layer (ARL) is used as a launcher for the irradiation and the reflectance measurement. The correlation between the denaturation of the tissue and the reflectance from the WVA is detailed.
