Abstract: The zero-point quantum fluctuations of the electromagnetic field in vacuum gives rise to a macroscopic quantum effect, as theoretically predicted by Casimir, the change of the boundary surfaces leads to the disturbance of the infinite zero-point energy of the electromagnetic field, and macroscopically a force can be observed. The Casimir force has recently drawn the focus of the intense theoretical and experimental attention in quantum physics. In addition, human-made metamaterials with controllable electromagnetic properties, namely left-handed materials and single-negative materials, were fabricated experimentally. A introduction to the above issues will be given in the seminar, followed by the investigation of controlling the Casimir forces via the electromagnetic properties of the metamaterials.
