Electromagnetic power flow between opposite sides of a lossy dielectric sphere using spherical vector wave expansion

This article addresses the problem of communication in near field region. The proposed example is the communication between two small antennas, which are modelled as an electric dipole antenna (transmitter) and a small box (receiver), near a sphere that models a head. Spherical vector wave expansion SVWE is used to calculate the response of the model and to investigate propagation of power. Influence of the orientation of the antennas on the propagation is studied. The effect of location of the receiving antenna on the amount of the received power is investigated too.
