Implementation of Poynting Vector Measurements
Abstract
This report covers the design, construction, and field testing of an experimental device capable of measuring the magnitude of the Poynting vector associated with an electromagnetic field. With mechanical manipulation, it can determine the direction of the Poynting vector. It is based upon theory which has been described previously. Tests of the final device demonstrate that it is capable of measuring this quantity with reasonable accuracy. The major limitations on its use result from the necessity for obtaining an accurate phase calibration of the two separate channels used for amplifying the signals received respectively on the rod and the loop antenna. Interaction between the rod and the loop does not seem to be a significant problem. The device has unique characteristics and a number of applications for it are indicated. Recommendations on improvements in the device which are desirable for general field use are included.
