N2 - This paper describes the development of a human electrical phantom in the low-frequency band. Conventional high-hydrous gel phantoms cannot mimic the electrical properties of the human body in the low-frequency band. Titanium oxide coated with antimony-doped tin oxide (ATO/TiO 2 ) was added to the high-hydrous gel phantom, and the electrical properties were evaluated in terms of the amount of material added. The developed phantom had an error of less than 10% in the range of 100 kHz to 1 MHz, which conforms with the electrical properties of human muscles. Particularly, at 125 kHz, the error was 2.71% and 4.35% for relative permittivity and conductivity, respectively. The variation in the electrical properties of the developed phantom was evaluated, and it was confirmed that sufficient reproducibility could be obtained.
