Correction to "An analytical approach to calculation of lightning induced voltages on overhead lines in case of lossy ground - Part I: Model development" [Apr 13 1213-1223]

The above-named article [ibid., vol. 28, no. 2, pp. 1213-1223, Apr. 2013] had an incorrect equation (11b). It is shown in the correct form here, using the same equation number as in the paper. All of the results in the article were obtained by using the correct equation and, therefore, are not affected.
