As one of the development of the future wireless communication systems, body-centric wireless communication using a device including a radio terminal placed in/on body is proposed -. In order to realize the wearable devices for the body-centric communications, it is apparent that examination of the antennas and propagation in the vicinity of the human body is very important. In this paper, in order to investigate the transmission mechanism of the wearable device for on-body wireless communications analytically, we derive the eigenfunction solution and high frequency asymptotic representation for the scattered electromagnetic fields by a dielectric cylinder and discuss them. By comparing the high frequency asymptotic solution to the eigenfunction solutions for the scattered field in detail, the composition of the scattered fields are treated.
