Abstract

A major characteristic in hyperthermia technology is the ability to focus heat energy on a small region around the tumour to be treated. By applying Kirchhoff-Huygens principle and the scalar theory of diffraction, specific absorption rate (SAR) distribution in a homogeneous muscle due to arrays of open-ended rectangular waveguide as direct-contact applicators (ORWDAs) at 915 MHz are calculated. The results are compared with that of a single ORWDA operating at the same frequency. The array applicators may offer improvement in field size and penetration depth.
