Outline of Final Research Achievements

A statistic model for the intrabody communication (IBC) channels are considered. It was clarified that the complicated probability density of the received voltage can be modeled by multiple normal distributions.
Besides, the conducted noise currents, which may affect the IBC channels, were considered. The currents flowing on a three-line AC cable in phase are defined as "three-line common-mode currents." Then, it was confirmed that the three-line common-mode currents are generated by a general AC/DC converter both via circuit simulations and measurements.
Furthermore, a circuit modeling technique for electrically-very-small devices was developed based on the method of moments.
