ABSTRACT
An experimental study is described, leading to the design of a near-field electromagnetic radiation probe. A passive field probe with fibre-optic link has been constructed for use in hyperthermia phantoms, i.e. for measurements in lossy media--saline was used in this study as a simulation of biological tissue. The realization of a closed electric circuit on the probe proved to be a major influence on the sensitivity and dynamic range of the probe. The experiments also independently confirmed the dipole length, frequency variations between 5 and 110 MHz and the temperature of the probe as important parameters.
