A system of four charged plan-parallel electrodes is used to generate a homogeneous electrostatic field. The influence of a cylindrical external body on the generated uniform electrostatic field is analyzed. The body made of different types of material is observed. The expressions for the field inside and outside of the cylinder made of perfectly conducting, isotropic dielectric and bi-isotropic material of Tellegen type are derived by applying the method of images. Numerical results of uniform field deformation, caused by the presence of external cylinder, are presented.
