Near-field measurement using Yee scheme and far-field imaging

摘要

In this paper, we propose a new method to acquire Poynting vector distribution by means of measuring electric(E) and magnetic(H) distributions in a near field. An experiment has been performed to obtain a near-field distribution for a transmission line having risers above a ground plane. Furthermore, we discuss on the relation between the near-field distribution and far-field imaging. We point out that the emitting field distribution is similar to the Poynting-vector distribution rather than the near-field distribution itself.
