Abstract: The influence of a conductor plate with straight slit on uniform electric field is studied by using Schwarz-Christoffel transformation and its inverse transformation on the complex coordinate system of the complex number. Furthermore, the electric potential distribution and electric field intensity distribution are obtained. The electric field line maps are plotted using the software MATLAB. On extent of influence of a conductor plate with straight slit on uniform electric field is researched in qualitative.

Key words: uniform electric field, a grounding conductor plate with straight slit, Schwarz-Christoffel transformation, electric potential distribution, electric field intensity distribution, numerical simulation
