Figure 9
Power emitted from the eight-element array (sample 4). The power follows approximately quadratic behavior as the number of elements increases indicated by the curve. Blue and red data indicate separate series of measurements uncovering the rings from left to right vs. right to left respectively. The black datapoints indicate the mean of the left and right measurements. The estimated uncertainty is propagated from the standard deviation values associated with the left and right averages. Results are normalized to \({P}_{max}\), the mean power calculated for 8 elements.
