Abstract
The analysis of a thermic end-fire interstitial applicator for microwave hyperthermai, i.e. an applicator that performs a tip-localized heating of the surrounding lossy medium, is presented. The antenna consists of a shorted coaxial cable with an annular radiating aperture at the end. the analytical approach is based on the equivalence principle, which leads to an integral equation for the equivalent magnetic current distribution on the aperture; solution is achieved by the method of moments. All theoretical results are compared to experimental ones, showing a good agreement in a wide frequency rangeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
