Thottappillil, R. and Uman, M.A. (2002). Reply to the ‘Comment on “Return stroke transmission line model for stroke speed near and equal that of light” by R. Thottappillil, J. Schoene, and M.A. Uman’ by B. Kordi, R. Moini, and V.A. Rakov. Geophysical Research Letters 29: doi: 10.1029/2002GL014758. issn: 0094-8276.

The ideal and exact solution for a vertical wire antenna of infinite length above a ground plane excited at the bottom, all conductors being perfect, is spherical TEM. Currents along such an antenna do not suffer from attenuation and dispersion. The energy lost due to radiation from such an antenna appears to originate from the source at the bottom. Practical systems are different from this ideal case because there are no ideal sources and no ideal conductors. However, ideal analytical solutions should be used, when possible, as a validation of numerical solutions in the appropriate limit.
