For the development of the human tissue-equivalent phantom in terahertz range, I have accumulated the complex relative dielectric constants of human skin, improved the measurement methods, and also accumulated the material properties of varieties of samples which may be materials of human tissue-equivalent phantom. For biological materials such as human skin, it was sometimes difficult to realize the measurement with good reproducibility. Thus I have improved the ellipsometry measurement and developed a system that can measure the complex relative dielectric constants with high accuracy for the soft, protean materials. Based on these results, I have developed a phantom which simulate the complex relative dielectric constants of human skin in terahertz range.
