Abstract
Near future, a further direction of mobile and ubiquitous communications will be integrated each other. As one of these forms, a wearable transmitter and a ubiquitous receiver with electrodes were developed. The signal is transmitted from the transmitter to the receiver through human body when a user wearing the transmitter touches the receiver. However, little is known about the transmission mechanisms of human body as the transmission channel. Therefore, in this paper, human body wearing the transmitter is modeled by the FDTD method and variations of transmission power caused by the differences of the electrode structure are analyzed.
