Abstract

In this study we investigate The Casimir force on the rough dielectric surfaces. In order to accomplish this goal we simulated a 2D rough dielectric surface in das-sarma model as one of the discrete models of MBE and then we calculated the Casimir force by using the Lifshitz relation when it is approximated for small separations. At the final stage we calculated the repulsive force of two surfaces as a function of separation. The results show that both forces relate directly to the roughness and change over separation inversely, but the attraction force changes over separation more rapid than the repulsive force.
