  7. Abstract:
  8. Boundary conditions on a background field can change structure of quantum vacuum such that cause the attraction force between two parallel ideal metal plates. This is known as the Casimir effect, and it has dynamic aspect that seen by changes in the position of the boundary conditions imposed at the time. In the static case, creation and annihilation of virtual particles leads to system pressure that can be negative (attraction) or positive (repulsive) with respect to parameters such as the shape and topology, the materials used in and temperature. In the dynamical case, particles are real and emits as radiation and pumps energy from vacuum. In this thesis, our first attempt isto recognize the Casimir effect. After that, we study its dynamic nature from mathematical and physical issues. Furthermore, specific cases that lead to the production of particles (photons) on electromagnetic background field, with high growth rates are more closely examined and numerical simulation have been studied. On numerical simulations, we have tried to consider the different conditions which are comparable with analytical predictions. Finally we discuss that this phenomenon is influenced by several parameters that can be followed considering all of the experimental results
