Abstract: The influence of a conductor plate with low ridge on uniform electric field is studied by using radical transformation on the complex coordinate system of the complex number, furthermore electric potential distribution and electric field intensity distribution are obtained. The electric field line maps are plotted by using the software MATLAB. On extent of influence of a conductor plate with low ridge on uniform electric field is studied qualitatively.

Key words: uniform electric field, a grounding conductor plate with low ridge, radical transformation, electric field distribution, numerical simulation
