Abstract

The main objective of this study is to assess whether two parallel metal plates implanted in the head region could be expected to cause SAR enhancements under UHF near-field exposure. In this paper, we achieve precise temperature distribution measurements for a physical head phantom implanted with two metallic plates using thermograph. The phantom was newly manufactured using silicone rubber and carbon material. In the measured distributions, temperature increase due to the metallic plates was clearly observed in the gap of two metal plates region. Obtained measurement data can be used for validation study for further SAR estimations using numerical analysis.
