Abstract: By means of theoretical analysis combining with computer numerical simulation,we study the electric field of a line charge and a grounding plane conductor with straight gap by using the conformal mapping.The electric field line and equi-potential line are plotted by MATLAB.

Key words: a line charged, a grounding plane conductor with straight gap, conformal mapping, electric field, numerical simulation
