Abstract

A comparative analysis of the near electric field generated by a three-dipole irradiator in a relatively dense dissipative dielectric medium such as fat or muscle tissues is performed. The irradiator is formed by uninsulated or insulated symmetrical dipoles and may be used in RF and microwave interstitial hyperthermia. It is shown that the application of the three-dipole irradiator may widen the area of comparatively uniform heating, It is shown that the microwave irradiator with a quadrature feed, when one dipole is an active reflector, has a high directionality in a dense dissipative medium.
