The outbound and local power emitted from a pair of identical, perpendicularly oriented electrically small TM dipoles are determined using time and frequency domain numerical techniques. Earlier work (1997) showed that a complete description of power in a radiation field required the use of three numbers, while the frequency domain mathematics inherent in the complex Poynting theorem provided only two; frequency domain mathematics lack phase information that is of significant consequence for certain antenna designs. In this paper we numerically model,using commonly accepted techniques, the simplest antenna design that clearly illustrates the differences in the time and frequency domain representations of power.
