Electric Potential and Field Distributions Simulation on a Barrier Separating Two Electrodes Under Different Constraints

In this paper, a simulation of a barrier inserted in between two electrodes was made. The simulations took into account different conditions of the electrodes (point-plane, point-point, circle-plane and circle-circle) and the condition of the barrier (a barrier with and without a hole and pollution in the middle of the barrier). The software COMSOL Multiphysics, 5.6 version was used to simulate the effects these conditions have on the distributions of the electric potential and field (E-field). The results show that there big changes in the distributions under the different conditions where it be pollution or a hole in the barrier or even the electrodes shape.
