文摘
- •
This paper for the first time derives electric field expressions in the monopole technique.
- •
Derive charge density expressions along the tall object and lightning channel.
- •
Very-close range electric fields are calculated based on this new method and compared with the results of traditional dipole technique.
- •
Provide an alternative explanation to the inverse of polarity of the vertical electric field at very close range from the tall object base.
