Modeling of Graded-Index (GRIN) Lens

Graded-index (GRIN) media, with smooth variation of refractive indices, can be used to e.g. make a lens with flat surface, or reduce the aberrations. VirtualLab Fusion provides a physical-optics modeling technique for light propagation through GRIN media. With the same speed but far beyond ray tracing, the physical-optics modeling takes fully electromagnetic fields into consideration, which includes the polarization crosstalk effects.
