The mutual interaction of plasma sheaths is investigated in our contribution. A two-dimensional particle computer model was used to solve the I-V characteristics of a small test cylindrical probe immersed in two different sheath structures-around a big cylindrical probe and near an uneven surface.
The effects that appeared were discussed for different positions and bias of the small probe. We interpreted the data obtained by a standard analysis of the computed I-V characteristics, and we say whether the trends of the plasma parameters obtained from the I-V characteristics correspond to real situations.
