In this paper, we have investigated the optical cancellation effect in rotating ellipsoid system, revolution parapoloid system, and bispherical system by coordinate transformation method. We found that the system would take on cancellation effect provided we design the dielectric constant and permeability correctly, that is, the light emission from one point of the system could propagate to the other point where the field of the light is the same as the field of the source. Especially, for bispherical system, the dielectric constant and permeability could be designed as a scalar, so the diffic...
