Focussing through a Luneburg Lens with a Tilted Plane Wave

The Luneburg lens is a famous example of a graded index media acting as a focusing lens. We want to demonstrate that it is possible in VirtualLab Fusion that these kind of inhomogeneous media can be simulated. While the Luneburg lens itself is radial symmetric by design, the component in VirtualLab Fusion is not restricted to that and also can simulate asymmetric inhomogeneous components. In this case however the inhomogeneity must be specified by the user e.g. through a programmable medium.
