Summary:
We developed a free-space type in vitro exposure apparatus for 60 GHz millimetre-waves (MMWs). The SAR distribution in the medium was numerically obtained by the finite-difference time-domain (FDTD) method. Temperature distributions were estimated by numerical calculations of the equation of heat conduction. The numerical results were also investigated experimentally by using two different methods of temperature measurement. Temperature elevation was measured by fluoroptic thermoprobes. Temperature distribution was measured by micro-encapsulated thermo-chromic liquid crystal (MTLC). It is found that MTLC has advantages over fluoroptic probes owing to the very high spatial resolution and quick temporal response which provide useful means for MMW dosimetry.
