摘要

It is shown that the expression of Shao et al. [2004] for the radiation component of electric field from lightning return stroke does not give the correct analytical expression for the radiation beam pattern for the traveling current source (TCS) model, even though their expression for differential radiation electric field is general for a moving current element. It is also shown that their expression does not give the correct radiation field pattern for a traveling step function wave whose magnitude is exponentially decaying with height (the modified transmission line (MTLE) model).
