Abstract: By combining conformal mapping and plane mirror method,the electric field of a line charge and a

ground parallel conductor plate with a ridge are solved,and several special features are discussed. Further,the distribution

of the electric field is simulated by using mathematical software MATLAB.

Key words: a line charge, a grounding parallel conductor plate with perpendicular ridge, conformal mapping, plane image method, the distribution of electric field, numerical simulation
