Abstract:

We received two copies of the discussion: one from the journal and a corrected version directly from Dr. Chatterji. Based on the differences between the two versions, we realized that our choice of wording in the paper could be improved upon. While we were careful in the paper to distinguish between a field and a gradient in a field, the reader may have been confused by our use of the word "potential" for both the field quantity and the voltage one would measure across the system. The first has both spatial and temporal dependence, the latter only temporal dependence. This distinction was also obfuscated by our omission of explicit dependence on the equations in an effort to achieve visual clarity.
