Rotating Optical Axis for Transformation Optics

Here we answer the following question: how general can we do transformation optics by confining the usage of a single type of anisotropic medium? We develop a scheme by using effective media of layers of varying optical axes. It extends the recently demonstrated anisotropic carpet cloak at visible frequencies by assembling small pieces of the same anisotropic medium with optical axes in different directions. A wave expander and a virtual shifter are designed as examples.
