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.
