Abstract

The electric field and charge surface density of a charge column-shaped conductor are solved by using the conformal mapping and transformation relation and its electric field distribution is simulated numerically by using the software MATLAB. Further more，the distribution curve of charge surface density is plotted.

Key words： charged column - shaped conductor; conformal mapping; electric field distribution; numerical simulation; charge surface density
