Abstract

This paper describes the application of a new hybrid method of moments, with generic and sub-gridded finite-difference time-domain approach (MoM-FDTD-(SG)FDTD) for modelling the interaction between an applied excitation placed in close proximity with an inhomogeneous human body model. The source is provided by a small low frequency RFID antenna tag, operating at 900 MHz. Near and far fields performance for the antenna are assessed for different placements over the body. The cumulative distribution function of the radiation efficiency and the absorbed power are presented, and discussed.
