In recent years, research and development have been actively conducted to utilize terahertz (THz) waves for next-generation wireless communications and sensing applications. Concurrently, safety guidelines for the secure use of THz waves at frequencies above approximately 300 GHz remain under active discussion. For these discussions, it is crucial to highly accurately evaluate the temperature rise in the depth direction resulting from THz-wave absorption in the surface layers of the skin. However, studies on tissue-equivalent phantoms in the THz region that mimic the skin structure remain limited; in particular, epidermis-equivalent phantoms for the temperature rise measurement that match the dielectric properties of the epidermis have not yet been developed. Therefore, focusing on the epidermis where the absorption of THz waves predominantly occurs, this study aims to develop an epidermis-equivalent phantom that mimics both the absorption characteristics and surface textures of the real epidermis in the 0.1 THz to 0.6 THz range.
