    "abstract": "The Casimir force for charge-neutral, perfect conductors of non-planar\ngeometric configurations have been investigated. The configurations are: (1)\nthe plate-hemisphere, (2) the hemisphere-hemisphere and (3) the spherical\nshell. The resulting Casimir forces for these physical arrangements have been\nfound to be attractive. The repulsive Casimir force found by Boyer for a\nspherical shell is a special case requiring stringent material property of the\nsphere, as well as the specific boundary conditions for the wave modes inside\nand outside of the sphere. The necessary criteria in detecting Boyer\u0027s\nrepulsive Casimir force for a sphere are discussed at the end of this\ninvestigation.",
