Rectangular Waveguide for Electromagnetic Oncology hyperthermia: Design, Construction and Characterization

This paper describes an applicator of electromagnetic fields for its clinical use in oncology hyperthermia treatments. The applicator is a rectangular waveguide working at 200 MHz. In order to reduce the applicator dimensions (8.5 cmtimes4.2 cmtimes16.9 cm), it was filled with deionized water. After designing the applicator, it was characterized for its clinical use. Electric field distribution, impedance, and calorimetric measurements are presented in this paper
